Is my fish preggers? (see details below)?

Question

I have two pearly-colored danios (I THINK thats what they are), they have orange eyes, one is bigger than the other, like 3 inches and the other is just a tad smaller. I have a 30 gal tank with 7 differents barbs, 2 silver dollars, 4 corys, a couple of plecos and a betta. Good-sized external filter system, large aerator stone, inch of gravel, 80 degrees, (no plants) and I've had it about 6 months and its a very stable community (maybe a couple of deaths after I got it stablized). The fish usually hang out at the bottom of the tank. Suddenly in the last 2 days the swollen orange-eyed fish is hanging around the top of the tank and its underside is very swollen while its companion is still slim and sleek and behaving normally, as the rest of the fish are. And I noticed its not eating at feeding times. I bought these two orange-eyed fish about 3 months ago as small fish. I had no idea they would get this big. Could this fish be pregnant and if so what should I do? Thanx.

Answer 1

If the fish is always around the surface and has a hard time swimming to the bottom and always floats back up, she/he has swim bladder infection. Normally when fish are pregnant they will hide alot more(from my experiance at least). If it is swim bladder infection, then you should perform EPSON salt dips/baths, there is no known cure, but these may help. www.google.ca www.yahoo.ca enter epson salt baths for info on how to perform these.

Answer 2

Definetly not pregnant.

Sounds to me like internal parasites. Internal parasite can overpopulate inside a fish's belly, that is what will cause a swollen belly, also will cause a fish to not eat.

To treat it you need to get medicated food, or medicine that you add to the regular food. Water treatments do NOT help because the parasites are in the fish's belly.

pearl danios only grow to about 2 inches. here is some information on them.

there is a good chance you have a pregnant fish -- other reasons fish get fat would be overfeeding, swim bladder disease (it would be swimming sideways) and dropsy (it would be more swollen than fat and its scales would stick out -- people say it makes fish look like a pinecone).
