The only stocking issues I might have are a bala shark and a kissing gourami who both came with the tank when I bought it off craigslist, and are both going to be looking for new hes when needed but so far everything is ok. And some people.might get mad, but this is before I knew, a green terror. He is definitely not a bully though. He only defends himself when attacked. He is NOT THE PROBLEM AND I KNOW MY MISTAKE OF MIXING NEW AND OLD WORLDS TOGETHER. But I have noticed that there is more aggression going aeoumd lately, but idk why. I am not trying to hide anything, and am sorry if I made it seem that way. And another thing to add to add, the store I bought the fish from that died first, two weeks ago, the fish just came in the day I walked in and they were acclamating the fish when I walked in, so the fish was dead when I walked in the store, he then sold me the one who was in the same bag at the other, so its definitely not the stores fault, probably the suppliers.
