Hi, I've had a tropical tank up and running for a few months now, and it started off quite well. The last month has seen quite a few problems, with some mysterious deaths, most of which seemed to be isolated cases with no common trends
Death toll so far includes (in order of death);
2 female guppies
1 platy
1 neon tetra
1 female guppy
1 male guppy (only just reached full maturity but with great colours) he will be sorely missed
I've only just joined this forum as of yesterday and am trying to gain some understanding into whats happening.
The male died 2 weeks ago following a big water change and a tank cleanup, i took out an undergravel filter, changed gravel, retaining 50% of the water with the fishwhich which i returned to tank after clean. Male guppy showed signs of tail rot which wasnt picked up until to late, i added melafix to little to late and he expired within 2 days. I completed 7 day melafix course just in case and did 25% water change on saturday. Had water tested monday, amonia, nitrite and ph all tested perfect.
Just noticed today that 2 female guppies arent right. 1 has a deteriorating pectoral fin and red gills, the other has red under gills on only one side. Both still active and feeding happily but this seems reminiscent of one of the females that died. The deteriorating fin is getting worse as i think a male guppy is nipping that location. Going to isolate her in a birthing cage as i don't have a 2nd tropical tank. Any ideas please?
