So I have my 75gal trop community planted tank that is understocked. I have a school of emporer tetras (5), a Royal Farowela, rubber lip pleco, 2 juli corries (4 more in qt), 1 Angelfish, 2 serpae tetras (i know they like to be in schools but I have also read they are notorious fin nippers, the two I have are not fin nippers and dont want to risk getting more that could be), 3 platies and 1 golden wonder killifish (had 2 but one jumped). The angel that I have is pretty agressive towards other angels but leaves the little fish totally alone, I had bought 2 angels at the same size (medium-large size) but the one I have now constantly attacked and eventually stress killed it so im not too inclinded to buy another angel. I also was going to add a school of 4 australian rainbows but they were sick and died in qt luckily. Could I get a gourami? (not a dwarf) Or a kissing gourami, which I have read can get pretty big and a 75 is the min size for them. I am also looking to upgrade my tank to a 110 tall in the next few days if all goes according to plan. Are gouramis compatable with angels and some smaller fish (smallest body size is probably the platies)
