Wasting disease killing my fish
I’ve got multiple tropical community tanks, and over the last 4 months I have had more losses than I can count.
It started just after I introduced 3 new fish into my 200L community tank. I initially put it down to an ammonia issue, but after a week or so passed, my water perimeters stayed within normal limits, but fish kept dying I started to worry.
I have now lost around half my tank from the 200L, I’ve got one of my old angels in a 50L (devastated) and as of today I’ve lost killi fish in a third 50L tank.
I must admit my biosecurity isn’t great between tanks, I use the same cleaning gear between them (oops I know bad).
On thing I notice before the fish die is they start to waste away, they lose their fat pocket and look a bit sickly, before suddenly dying. I have no idea what the next step is, if it’s a bacterial infection (TB for example) where do I got to test for this or what do I do.
I guess my question is, please help me figure out what my next step is. I have already lost so many animals and it’s heartbreaking to have to keep seeing them die or having to euthanise them. Any help would be appreciated!
