Hello hello
My boyfriend has had this fishtank for idk how long but now we live together and these fishes are now my step children ? so I am trying to learn about them etc etc. so we bought new fish but of course he didn’t clean out the tank BEFORE putting them in and our catfish died any reason why? And also we have this fish that I believe is a tetra? He has a huge belly & I read it could be dropsy? But I need opinions. Thanks!
