I am new to this forum but anyway, I have a 10 gallon tank which has started to leak and it has a marble angelfish the size of a dollar coin, and two male dwarf gouramis. The gouramis are somewhat fighting. One male is a bit smaller than the other. I just recently got them since my tank was a bit empty. Are gouramis especially males fight for territory. I am getting a 26 Gallon Bow Front soon but don't know when. Do you think they will stop fighting if they had more room. Maybe adding females to it would help or would they be harrassed?
