Hello all,

I'm looking into setting up a tank to house some Heterandria formosa. Right now I have a planted 10 gallon and a planted 2.5 gallon available for these fish. Would the 2.5 gallon (heavily planted) be large enough to maintain a stable breeding colony? Or would it be better to designate the 10 for that purpose? Thanks in advance for your help!

Thanks for the tip. It's good to see the NFC site back up and running!

The 2.5g would work for awhile but if you can dedicate a 10g for them, that would be even better. Just minimize the amount of males so they don't pester the females too much.

I would go with the 10 gallon as these guys look great as a group in a larger tank. I have mine in a 20 gallon and they are really fun to watch and keep. They are one of my favorite fish!

FWIW, I've kept a colony of Heterandria in a 2.5g for about two years now. I originally received 11.1 animals, of which several of the original males died within about a month (maybe they were older?). The rest did great and the population has varied between 7-15 animals at any one time. It seems several of them died over the winter. I'd actually like to infuse some new blood if anyone has some spares they'd like to get rid of...

Shoegazer,

How do you receive 11.1 animals???

OTdarters,

I have a small breeding colony in a 2.5 gallon tank. It's a 2.5 gallon glass "hurricane" that I have a sponge filter and some Java Moss in. I change about 40% each week and the fish seem to be doing great. I may even "unload" some of the young soon.

Yeah, it boggled my mind as well. I purchased a 10 lot from Sachs Systems Aquaculture, and they sent 11.1

The decimal system to denote the genders of specimens is standard in the herpetology field, and it often spills over to the fish people, especially where one culture facility overlaps them and the staff are accustomed to it.
11.1 should have indicated 11 of one sex and one of the other, although from the description it doesn't sound like it quite did so, unless you got 11 males and one female, which would have been very odd.
Anyway, if you should ever see a list of reptiles available at some facility, you'll notice that each species has these numbers beside it on the list. 3.4 means 3 males, 4 females, for example.

Oh, right...

I had taken BTDarters' question as a commentary on the unlikely ratio of eleven males and one female, not considering that he may not understand the decimal notation.
