might be a bit crouded, plus, ull have to keep it pretty clean, watch out for nitrates, nitrites, and ammonia, tehyre your killers, and btw, keep the ph between 6.7 and 6.8. if you keep there at correct levels, you can keep any fish in any tank, as long as it doesnt outgrow the tank, (should have fishes length x 2 = width of tank)
hope this helps
