Fry With Clamped Fins

[julia298]

Some of my guppy fry have clamped fins and they appear sort of fuzzy along the top of the body.

They were in a 25l tank on their own. I tested the water amm 0, nitrite 0, pH 7.6, nitrate 20.

As I have a fish with an ulcer I moved the fry out so i could isolate the sick fish. They are now in another tank with same water stats but nitrate 10.

Theyve been in there 2 days now and fins still clamped.

Should I add some general tonic? I cant see any other ymptons of a disease.

the fry are about 4 weeks old.

Sadly it sounds like columnaris.
Clamped fins are a sign of stress, so check water quality, is there enough aeration in the tank.

Can fry survive that with treatment?

Fry can be tough so i wouldn't write them off yet, they will die anyway if you don't treat as columnaris is nasty. Good luck.

You will need half a dose of finrot med by interpet, plus half a dose of anti internal bacteria med by interpet, plus you will have to increase aeration, turn temp down 2 degrees.

Just wondered - what does a 'clamped fin' look like?...

When the dorsal fin lays down on the body, instead of being up right.

With the fry, i noticed 1st that their tails were not fanned out anymore. theyre now all tight and pointed looking.
