Sick Leopard Danio, Body Fungus?

[nem2k2]

One of my leopard danios is swimming slowly around the bottom of the tank and has what seems to be a small white growth in the middle of its body. It is about 1-2mm in diameter and sticks out from the side of the fish. The fish also looks a little plumper (but not much) than usual and its tail is sort of bending upwards. My other leopard danio recently died from dropsy in the same tank.

Any ideas what's wrong? Is it body fungus?

Nem2k2....sorry to hear about the danio. It certainly seems like there is something going on here. At the minimum, I would isolate your danio into hospital tank and add aquarium salt. Can you give us more information to go on? See the post suggestions above, eg, tank size, how old, params? I would be leaning bacterial over fungus as this point. SH

Hi steelhealr, thanks for your post on my gourami thread

Tank stats are:

Tank size: 96L
Occupants: 4xclown loach, 8xneon tetra (moving to a new tank soon), 5xzebra danio, 1xbristlenose pleco
pH: 7
ammonia/nitrates/nitrites all fine
water changes - 25% at least once weekly


I also have a sick clown loach in the tank too, I posted a thread about him here but he seems to be a lot worse now, tonight when I fed the fish he wasn't really interested at all, he just lay on his side. His breathing is constantly very fast, over twice as fast as the other loaches

Well that tank is way to small for four clown loaches they need room to move, the growth is it fluffy, does it have a red edging or red centre to it.
If the clown loach is breathing fast and lying to one side i would issolate him as he's not sounding too good.

Sadly the danio had developed dropsy (he reached the stage where his scales were sticking out like a porcupine) so I had to euthanize him

I have moved the loach to my quarantine tank (which is handy because it has a snail infestation!). Anything in particular I should do or just wait and see if he settles down and his breathing returns to normal?

Are they any dead snails in the tank as they can cause toxins in the tanks which can kill fish, i would do some water changes and get the snails under control.

No, there are no snails at all in the main tank (aside from empty shells from the snails I feed the loaches from time to time), and I cannot see any in the hospital tank anymore, no doubt because the locah got hungry.

The loach seemed to settle down after being in the hospital tank for a while, so I have put him back in with the other loaches to see how he goes.
