20g Community Aquarium

I suspect they say that because of male 'aggression.' As in most Nannostomus species the males establish mini-territories. I haven't found this species to be as problematic in that way as, say, N. nigrotaeniatus or N. mortenthaleri. I've kept N. rubrocaudatus successfully in a 29 high, which was 30" (77cm, I believe). I think your setting provides so much cover, I'd try it.

Rereading your post...Isn't a 20 high 60cm (24") and a 20 long 77cm (30")?

You are correct. I got mixup. In that case, I am sure that it must be too small. I may have to put these in the new 20g long I am setting up.

I got puddled about it too, that's why i wanted to check with you. I reviewed several of those seriouslyfish tank size recommendations for the genus and have issues with several of them, but that said, I think that for several reasons, including how pricey this species is, it would be too risky to attempt it.

I liked this picture of one of my shrimp I took today.
