*Hello everyone !
As said in my presentation post, I just move from France to Québec and in the same time became really interested in native fishes. One of my favourite family is definitely the darters. There's a lot of Johnny darter (Etheostoma nigrum) in the river where I live, and I decided to start a tank for them. My goal is to conceive the tank to please them first (and maybe, if I'm lucky, breed them). They may have tankmates or not, I'm not sure yet (maybe a small school of Fundulus diaphanus, are I found them in large number in the same place as the J.D.).
As I'm a student, I have two main constraint : place and money. I found a second-hand shallow tank and thought it'll be perfect for darters as it optimize the floor area. I also bought a used Fluval 106 to have a good waterflow. I had some filter media from an old tank of mine which has been running for a year to "boost" the nitrogen cycle. The sand is a sandbox one (free of pollutants), so much cheaper than fish tank gravel and really looks like river sand (and already washed !). I add a simple LED bar (640 lumens, 3000K) that should be alright for the few plants I'm gonna have. All rocks, wood and plants come from the river.
So, here it is, just after setup (still cloudy):
L*w*h = 78*29*24cm = 31* 11.4* 9.4 in
About 54L or 14Gal.
I tried to replicate the biotope where I found JD here : a sandy river bottom with a lots of dark schist-like rocks of different size. I used the rocks to create 4 caves. I often found them next to the river bank, and so I tried to mimic it with the wood and some plants. To date I only have a few but I will add more.
Time for questions !
- How many JD could I keep in there ?
- If I want to breed them, should I leave them alone or could I had some tank mates ? If tank mates, which one ? (Next to my place I already found some Fundulus diaphanus and small minnows).
- Do you have any suggestion to improve the setup ? More rocks / caves ?
I look forward to have your comments and advice !
PS : I'm used to wait, and as it's almost winter here fishes will probably arrived only in a few month !
