Sick Rainbows ...again

[ArielC]

I have no idea whats been bothering my rainbows for the last 4 months. Each fish has been dying one by one, the first four within a month (maybe three months ago?), this last ones had it for two months. I just dont want my rsinbbows to keep dying.

Symptoms are as follows

one protruding eye, doesnt look clouded or deformed like popeye, just stuckout a bit, looks normal untill you get a sideveiw. no bleeding or swelling.

some protruding scales on the side, looks similar to parasites under the skin but i used a magnifying glass and can just see five or ten stuck out scales. (in a group)

Back very arched, sunken in belly, getting worse all the time. lost the traditional rainbowshape. not a squiggly line like in some cases, just one, continuous arch.

only kills one at a time, only kills rainbows.

long lived disease, kills slowly.

fish hangs around at the top, gasping for air a lot, the gills flapping madly.

Dark greyish in color

has been a bit lumpy.

Im so afraid im going to have to kill this fish. Ive never had to kill a fish before :[

ph- 6.8
hardness- soft/neutral

To ne at this moment in time it sounds like fish tb, dropsy, popeye, sunken in belly and bent spine.

Just looked at the tb site and it seems to fit it.

should i euthanize the fish? and once ive done that, should i treat the other fish?

You can treat the tank with minocycline but it will wipe the bacteria colony out in the tank, good luck.
