Sick krib?

Badmans Tropical Fish Message Center: Fish diseases : Sick krib?


Wednesday, February 27, 2002 - 10:59 pm
I bought a pair of wild caught kribs from my LFS a few weeks ago. The male turned purple and died after about 2 weeks. The female is acting kind of strange. She doesn't have any visible signs of illness (ie. no paracites, streaks etc.). The only thing that's stange, is that the fish is swimming by only moving its pectoral fins and it just floats vertically. I have no idea what is wrong. I read that wild caught species tend to get sick a lot, however i don't see any signs of sickness. The fish seems to be eating, well trying to eat at least. I highly doubt that there is something wrong with the water because i have other kribs and they're doing just fine. So if anyone knows what might be wrong with my fish please let me know. I would really like to try to save it.

My guess would be some sort of internal problem. You don't always see signs of trouble, and this can make it hard to figure out what is wrong. With any wild caught fish, especially those that recently arrived and haven't been in captivity for too long, its not a bad idea to feed the fish some sort of medicated food to treat for internal parasites. Parasites aren't always problem, but preventative "maintenance" on wild caught fish is always a good idea...especially when you get into those $100 wild caught African cichlids.
Sometimes simply going from one tank to another can cause wild caught fish, or any fish for that matter, to become stressed and more prone to diseases.

As for a medicated food, tetra used to make a good medicated flake food, but have since stopped making it, I think Tetra was bought by another company. Anyway, I don't really know of any other brands, so now you're stuck with making your own medicated food, which luckily, isn't really that hard.

I agree about the internal parasites being commonly found in wild caught fish(many fish farms treat with an external parasitic wash and problems don't really show up for a few months), however the funny swimming really points to swimbladder disease. Symptoms are a loss of balance and fish swimming upside-down or on their side. It can result from either poor water conditions, poor handling, breeding or fighting per my book. If you just got the fish chances may be it was handled roughly between the dealer,LFS store and your tank. My book suggests isolation and treating with an anitbiotic, but it also says if no improvement in 7 days eutanasia should be considered. I think if your fish is not scratching and does not have strange looking feces I would lean more towards the bacterial infection. You say you also have other krib, so make sure there is not any fighting going on when you aren't looking. Most cichlids will pester and fight with any newcomers.
