Acceptable fish load
I am in the planning stages of setting up a 20 gallon planted tank. I want to go low tech (no co2, medium light), and was thinking of using java moss, java ferns and some type of grassy plant. Since the plant selection was sort of asian themed I was thinking of going with that theme overall. Would a 20 gallon tank be too small for 6 tiger barbs? Also, do you think I would still have room for some kuhli loaches and a shrimp or two? Would the barbs mess with them? I would want to have at least 4 or 5 kuhli loaches. What do you think?
