Hi everyone. My adventures to redoing my 45 gallon aquarium have gone awry. I have 3 bn plecos, 2 honeys and 3 albino corys, there was 5 but two died and 3 dwarf puffers (which my lps said would be okay in this big of a tank, I told them about my other fish). I don’t know the water parameters yet. I will be doing my tests tomorrow. As for right now I have a big problem. I have a dwarf gourami in a quarantine tank right now who was originally with everyone else. They all got along great. Fast forward about a month (December 2022) I went away because a family member got ill. My friend looks after my fish tank because they live with me and it was easiest. My dwarf gourami is locally bred and I’ve had him since September 2022 with no problems. Now he has a large stomach, which I originally thought was constipation or bloat so I tried treating it with peas, he ate one but no change. Now I have the same issue with a honey but in the earlier stages. I had a two corys died, one in the tank with the dwarf gourami and one with the honeys. My friend didn’t take either of the corys out and I’m now wondering if the two gouramis tried to make a snack out of the poor corys? Maybe that’s why they are sick. The corys were about 4-5 years old so it was most likely natural causes. The dwarf gourami is a neon blue and the honeys are reds. I need help. The honey is eating and pooping fine. The dwarf gourami is not doing either from what I can tell.
