You should get all the info you need and more if you search for Erica Lyons Elassoma threads. The short answer is yes, they will eat their fry. Some people put a lot of work into breeding them, and separating the fry from the adults to maximize fry survival. Others take a more laid back approach, and figure that enough fry escape predation that the colony will sustain itself. The laid back approach requires either a lot of plants, or a lot of other structure to provide enough cover for fry to survive. Plants are typically the preferred cover.

I have personally witnessed an elassoma gilberti (gilbert were the same as elassoma okefenokee until the species was split in 2009) female eat either her own or her sister's fry.

My suggested method for breeding elassoma is to put adults into a tank and then, a month later, remove all the adults. Feed the 'empty' tank vinegar eels, microworms, baby brine shrimp, etc and two months later you will have around 20 juveniles per adult female.

When I tried raising the adults in the tank with their fry they would hunt down and eat them all. I lost a colony to no fry production in that manner; they just eventually died out. Their life span's about two years max, so if you're not producing fry soon you don't have any fish. Some people have had success with adults in the tank with eggs, but if you don't see any new juveniles within six months, act fast or you soon won't have any adults. All it takes is simply removing the adults from the tank to produce quite a lot of fry.

wont the un-eaten micro worms die off and pollute the water? i heard people say that the parents wont eat their fry's? damn they didn't know anything after all cause i had them for over 6 months and not see 1 fry... 4 males and about 7 females in a heavily planted 10g tank. did a cleaning of the tank today and found a new born fry still having the egg sack attached to him so i took him out asap just thinking it was better to take him out but if there is 1 there is more somewhere in the tank xD....


also would they breed in a acrylic yarn breeding mop?

They breed anywhere and everywhere. The egg production isn't the problem.

If your tank's been set up for a while and the filter (which I hope the inlet has some mesh over it to avoid sucking in the babies) has been set up for more than a month, then you've got nitrogen processing bacteria. The ammonia from microworms, vinegar eels, baby brine shrimp, etc will be processed by that bacteria same as whatever food you're feeding the adults now is. Nitrate, the end product of bacteria ammonia conversion, is then removed via water changes or being eaten by live plants.
The LC50 of ammonia, or the amount that kills half the population in 72 hours, is 0.43 ppm according to http://www.ncbi.nlm....ps LC50 ammonia The LC50 of nitrate is 4453 ppm.

Myself, I employ some rather fantastic plant ammonia processing. More info here http://www.theaquari...ical_Filtration and in Diana Walstad's book Ecology of the Planted Aquarium. The gist can be gotten from table 2, which shows that water lettuce absorbs even 26 ppm ammonia in 4 hours.
This means plants are awesome, and explains why my tanks are just plants and an air stone and they have healthy fish.

i had them for over 6 months and not see 1 fry... 4 males and about 7 females in a heavily planted 10g tank.

Stick the parents in a spare 10 gallon and feed the 'empty' tank. You've got lots of fry in there if you see one.

i'm thinking of removing the parents to their own small tank... not sure if they are all alive tho cause its really heavily planted and they hide a lot or most of the time...

As one of those "laid back folks" that Skipjack mentioned... I think you have too many adults in a ten gallon tank to successfully get fry. You need to thin out your adults to multiple tanks (or of course, just do like Erica says and move them all to another tank... you definitely have fry in there that you cannot see...

What do you feed them? I found they were a lot friendlier when I fed them grindal worms. Once they figure out how tasty grindal worms are, they'll come forward to the front even right in front of you to eat them. Live worms make keeping elassoma much more fun.

Here's a video where you can see they don't flee during feeding time.

mines come out when i feed them also but i feed them blackworms once or twice a day and some times i feed them daphnia instead of blackworms at times... they go crazy for lice food...

Yup. If you keep hand feeding them like that, they get used to you being there. Some will even learn to beg for food when you're there. The babies raised in your tank will be tamer than those gotten elsewhere.

Elassoma eggs are weakly adhesive; some may stick to the yarn and not fall through the mesh

My elassoma eggs always fell through all the way to the ground. The one time they stayed up in the plants I took a photo, because it was weird. They were sitting on cladophora algae. Sitting on, not stuck to. When I sucked them with a turkey baster, they came right off into the baster.

They were fertile, I hatched them.

Am I saying they won't spawn in the mop? No, they'll spawn anywhere there's a shadow. If the mop is where the shadows are, they'll spawn there. The eggs won't stick to it, though. They'll roll down and sit on the black mesh. You gotta be careful with that mesh; if the female or another male sees an egg sitting on the ground on top of the mesh not fallen through, it'll eat it. The eggs are 1.5 to 2.7 mm in diameter when laid, see this table here: http://www.nanfa.org.../elassoma.shtml

You're going about this in a very complicated way. I'm telling ya, it's really really really not hard to spawn elassoma. You put the parents in a tank for a month, you pull them out and put them in a different tank. Voila, 20+ juveniles per female. You don't have to do any of this complicated mop stuff or that bottom mesh layer stuff. Don't use gravel; if the egg settles in between two rocks it'll suffocate and rot. You can use sand, pure clay kitty litter, or a bare bottom. Any shadow will do. They'll spawn under a plant leaf, under a yarn mop, under a statue that says "NO FISHING". Any shadow works. As long as they're well fed, they spawn basically continuously. Getting eggs is not the problem. It's knowing to remove the parents so the fry don't get eaten. Try a once a month rotation style, moving the adults to a new tank once a month.

I am not advocating this method, but I will tell you this:
I stuck five elassoma okefenokee in a bucket tank and ignored them for a month and a half. And by ignore I mean I fed the adults bloodworms like once every three days and never fed fry food. I fed the plants fish flakes every other day or so. A month and a half later I took the adults out, kept scooping, and recovered fully 100 juvenile fish.

Elassoma by all rights deserve to be considered beginner level fish. I fed the fry vinegar eels every day after recovering them, then moved them onto grindal worms once they were large enough. I sold probably ten different auctions on aquabid just from the fry I recovered from that bucket. Easy peasy fish to breed. Don't be scared, you can't mess it up. Just take the adults out. That's the only 'trick'. Took me three years to figure that one out. Since I have, fry galore. Before I did, no fry at all.

Your fry separation method might work, but that tank has no ammonia processing. The reason the fish do so well in my tanks is instead of that yarn mop, I use ceratophyllum. Replace the yarn with ceratophyllum and replace the mesh bottom with a flat glass, sand, or kitty litter bottom, and you'll have a great setup. Choose wide instead of tall tanks and you won't even need an air stone. My bucket tank didn't have one. *nods* As it is, I don't know how the larvae are going to escape from the mesh. You're gonna trap them down there; they're bigger when they hatch then they are as first laid eggs. Unless you remove the adults and the mesh divider the moment you see eggs, I just see them getting stuck and dying down there. The eggs hatch in three days or so, then they need food like crazy. Detritus from plants is a good first food, as demonstrated with the success of the bucket tank.

well my tank with the mop is a harvesting tank... once the eggs fall down i will move the mesh up and harvest the eggs to their own tank, this way i can focus feed all the frys their own food without other parents or bigger fish taking up all the food... and i can have a empty bottom tank for the frys and do a cleaning easier then with substrate... i have 4 of these tank setup right now exactly what i showed in the picture above with the mop, 2 is for my celestrial pearl danio breeding and i have 2 spear which i plan on putting the parents into for breeding....



its a 7 gallon tank (24" x 24" x 10" high) with the mop, is it ok to have 2 males and 4 females per 7 gallon tank or will the males kill each other?






also the reason why i dont put live plants is cause they will die off and light isnt on for to long like 4 hr's a day 2 in the morning and 2 at night... why? cause the longer the lights are on the more algae that can grow... i'd like to keep a clean breeding tanks for my stocks... =)

I see no reason why this won't work just fine. I suspect that people like the live plants because they provide a lot of area for algae, and whatnot to grow, which in turn supplement the fry early on.

Male elassoma never kill one another. They're all show, no bite. You will just probably not have enough space for both males to spawn. It's likely that one male will color up and the other will be submissive colored. Divide the sight lines a bit more and both may potentially claim a territory. Two mops? I dunno.

Now that I know the mesh is removable, I'm changing my earlier opinion. That sounds like a good setup. If the mesh is removable then I can see what you're saying. It would be a big advantage to be able to separate the eggs out from the parents without having to physically remove the parents from the tank and put them in a new tank. Your mesh bottom solves the problem of 'what tank should I put the parents in next?" Instead, you just remove eggs when you see them and then you have a tank for small fry, a tank for medium fry, and a tank for juveniles. Yes, that would work quite nicely. I can definitely see the advantages. Can you show us how you built those tanks? I'd like to try them.

Also I never need to perform water changes, ever. No ammonia spike kills my fry, ever. Gotta love that convenience: feed but don't clean.

If you want to chat about plants, I'm here for you. Long story short an $8 Home Depot clamp light with a 1600 lumen daylight spectrum bulb for around 8 hours a day combined with nonzero nitrate concentration would grow your plants great with no algae. Ceratophyllum's big problem is often either not enough light, or the dissolved nitrogen (ammonia, nitrite, nitrate) drops to 0 ppm. Without roots, it's dependent on the water column nitrogen to make new proteins. So you'll catch me feeding the fish tanks with flakes every few days, not for the fish, but for the plants. Fish flakes are a nice nitrogen source for the ceratophyllum. It also feeds the snails and copepods, which elassoma eat.

to make the mesh bottom in my take is quit easy, you just need egg crates to make the base then go to any Michaels and buy some plastic mesh in the sewing area and tie it to the egg crate base and put some legs on the base to keep it about 1-2" from the floor and that's about it....


you can cut the base in half to make it fold-able and you wont need to take it out of the water just fold it up and it acts as a place to hold the parents while you harvest the eggs...




but for growing plants, thats something i do for years now just didn't want to mess of dying plant leafs and fertz the plants for them to grow xD here is a picture of my main display tanks
