I was wondering if it were possible to keep these in a 30 gallon long(3 ft) as a species tank. I don't think I can fit 5 species in my 55 with a 1:2 ratio.
I've never heard of people doing that species in a small tank. I think they get pretty big. I wouldn't do it.
Your 55 (in us gallons) could house about 15 fish.
