I would guess either a tumor or ulcer... that’s not cool... I guess the question boils down to..
1. Should you do anything..
2. How long will the fish live...??
Sweet setups! This is my dream fish room build! [emoji23]

My dwarf gourami has been acting a lot different lately and has some of his top pectoral fins missing... He is in with a community fish tank setup. I don't think he is getting bullied. He just sits...
My gourami started out looking like that but then got a bloat like stomach.. here is a similiar pic

I have been noticing in my 90 gal community tank that fish will die but Ill never have to find them or clean them "rid" them of the tank...? I wonder where they go..? I do have a couple different...
Yeah you will want to jump start the cycle on that tank by getting a chunk of some other filter media that has already been used quickly. I'm guessing the fish are just having issues with the water...
