Neons Dying

[crystalrainbow]

i have recently moved house , had my tank and fish in tempory residence, all fish( 2 zebra danios, and9 neons) survived all the moving and change of waters, did a total water gravel plant change when moved into new house as tank had been sitting in sun and was riddled with algae, still all ok, for 2 weeks, bought some new fish, 10 neons, 2 platys, 2 black mollies and a siamese fighter. all is now not well.... the neons are dying off at a steady rate, suddenly, with no sign of illness. on netting them out of tank they all look as if they have "split" down their belly?? they are still very colourful and not being bothered by the other fish. all other fish are dare i say it, well. i'm not over feeding, only thing different is natural plant, could they be gorging themselves on it, and popping?? i just dont know? any ideas please.

Did you add all of those new fish to the tank at one time?

What are your readings: pH, ammonia, nitrite, nitrate?

yes all fisha dded at same time from same shop,
just off out to get new water testing kit, mines years old and doubt accuracy.
i have just read this article--

Neon Tetra Disease
Neon Disease is caused by a parasitic single called organism called Pleistophora hyphessobryconis. The cell, releases millions of spores in to the water during reproduction. The spores are consumed with food by the fish where they then enter the intestine. The spores grow and replace the muscle fibers weakening the fish. If an infected fish becomes wounded or dies, the spores can escape and infect a new host.
Symptoms: Pale white patches appear under the skin beneath the dorsal fin. The fish also becomes emaciated and may swim erratically.
Treatment: Commercial remedies are usually ineffective as by the time diagnosis is confirmed the fish is too weak to be saved.


if it is this , will it affect other fish apart from neons? what do i do from here?

I don't know much about NTD, but neons aren't a very hardy fish. When you moved the tank, did the gravel change, etc., did you have the filter unplugged for a long period of time (more than a few hours) or did you change the filter / filter media?

My guess is that if the filter media dried out or was deprived of oxygen you're going through a new cycle and your ammonia/nitrite levels are pretty hight.

If you kept the filter running and media intact, it's probably just a case of adding too many fish at once. Adding one or two fish at a time gives the filter (beneficial bacteria) time to adjust to the additional bioload without having a significant ammonia spike.

you said you did a complete gravel change, did you change the filter media at all? could be the betta/fighter, they don't do well in commmunity tanks and will kill other colourful fish
