Sick Fish - dark swollen area under scales on abdomen

[Sick_fishy]

I've had the same 5 goldfish for around 7 years now. Recently one of my fish has started to become slightly swollen in the abdomen area. It seems that the swollen area is a dark colour under the scales.

I lost one fish not to long ago to a very similar problem. At first I thought it could be old age but now I'm wondering if it's a disease. Is there anything I can do to fix my fish? Should I separate it from the other fish in case it's contagious?

My sick fish is showing no other visible signs of being unhealthy.

Please help!!!

Dear sick fish,
In my opinion, ur prob is becoz some digestive prob which have been in the fish itself for sometime... I would like to recomend u 'SWIMBLADDER TREATMENT' number "13"... u can give it a try... I heard from my friend which has something similar as ur prob and he told me his fish is in good shape after using it... Hope it helps u too.. May ur fishy be well and happy...

IMO, u have a bacterial problem. Sounds like dropsy. I suggest u give the tank a good clean. Take out the gravel and give it a good clean. Try some Furan or Tetracycline if the problem persist. It may just be due to aquarium hygine....

good luck mate.

Hey Kevkoi... ;p What's Furan and Tetracycline??? And the usage??? Thanx in advance...

[kevkoi]

Both are antibacterial remedies. Tetracycline is an antibiotic. It's quite commonly available, but it's a bit outdated today as many of the bacterial strains are resistant to it already. Doxycycline is better, but need prescription to get them.

I believe Furan treats gram negative bacterial problems and tetracyline is a broad antibiotic which treats both gram negative and positive bacteria. Me no doctor so I may be wrong....
