Hi!

It looks like a bacterial infection to me!
Cheers

it could be septicemia, a bacterial infection. there are lots of medications you can use. i've had luck with maracyn2.

I had two cories in quarantine after bringing them home. Same thing. My eyes aren't the best, unless I get right up close to them which I couldn't do at the lfs. I brought them home, put them in q-tine and had a perception even while they were in the bag that they seemed off, but thought it was just the stress of the move. The other cories I brought home were still all of 15 minutes before they congregated and started exploring their new home. These didn't they were just still.

One had bad coloring and both had a small blood point at the base of one or both pec fins. I put melafix in thinking it was from the net as one had gotten stuck at the lfs. I noticed the heavy breathing the next day. Ammonia, nitrite, were 0, and nitrate at <10ppm. They still weren't active that day, but I thought they were just taking catnaps. However, I noticed they hadn't changed positions, for up to 10-12 hours at a time. The next morning I saw another small area of blood on the side of one and with that began treatment with Maracyn and Maracyn 2 at normal strength.

6 hours later, one had lost his orientation and was on his side. After watching him slowly expiring for 5 hours, I finally euthanized him with a solution of vodka and clove oil. At that time, I noticed the other one was also disoriented and had a much larger blood patch that had developed above one of the pec fins and behind the gill. I decided to euthanize him rather than let him suffer.

I believe it was some type of septicemia. I have since learned that a better treatment probably would have been something like Mardel's Tri-Sulfa or other sulfa based antibiotic. If you still have more cories getting sick, you may want to try this. I was told by another lfs that sulfa drugs seem to work better for septicemia.

The lfs offered to replace free of charge, but I am hesitant to take any more from them as septicemia needs a pretty bad environment to break out in. He had the fish for one month before I got them.

Hi bathos,

I suppose with the lots of medications that you mentioned, it would be antibiotics? would appreciate if you could share a little bit more with regards to this as I know of one little fella who has a red spot on the belly... which does indeed looks like infection to me (untrained eyes).

thanks very much in advance!

cheers

yup, antibiotics. fish i got never had so much redness and bleeding though. i guess i either caught it real early (i'm pretty observant when it comes to my fish) or for some reason the infection wasn't as bad.

Nautica: do you know when the fish got to the LFS? my favorite LFS generally sells their more unusual cories in a day or less. if the fish got to the LFS the same day you bought them, they could've been in bad conditions at the wholesaler's place.
