Greetings all. I have a 50 gallon curved front tank with 2 aquaclear 50g filters on there. One has charcoal the other does not. Temp stays at about 70 deg. Lighting is a 50/50 Actinic daylight bulb. Light and bubbler with 2 8" strips on each side of the tank with large bubbles run on a timer from noon to 9pm.
8 neon tetras (a few weeks ago had 10)
6 tetra skirts (2 white / albine, 2 zebra striped, 2 glo)
5 male guppies (seems to be enough of a school they do not fight)
1 bristlenose pleco
1 other pleco type catfish that looks like a blackish white and brown with a horizontal stripe4" oto forgot his type
Substrate is about 3 inches of gravel. Have an algae ball and a live plant. Try and change weekly to two weeks at 20% always vacuuming gravel.
Few weeks ago had a third glo tetra seem to have swim bladder problems. Started to corkscrew, swim sideways float to the top and such. He eventually died and got pulled pretty quickly. Subsequent research leads me to fear it was a parasite.
In past 2 weeks have had 2 neon tetras die for no apparent reason. Nobody in the tank seems to be nippers and they were pretty safe in their school.
Today found a very lethargic oto lying on his back until disturbed then swims around. And a glo tetro losing the roundness over his eyes, now looks more angular. This poor guy kept getting stuck on the filter. No apparent discoloration or fin nips.
Did a 15 gallon change and replaced carbon and put in a ammonia absorber. Vaccumed out the gravel real good as well.
Further inspection shows 2 neon tetras with 1 bright white spot each on flank, one near gill the other at fin joint. This is a bright white. The type of bright white that you can spot across the room with the actinic bulb. I also say on 2 of my glo danios (blue and purple, supposidly the bigger hardier ones of all the colors) that their stomoach areas are losing their color and turning pale white. No noted swimming problems to these four fish. My other 2 glo danios do not appear to have same issue.
I will be working on getting all 6 into my 2 gallon hospital tank. But that is way to small for all of them!
Is this parasite? Neon tetra disese? My imagination? Thanks for the help.
