The gf has a 45 litre bio-orb type thing,
2 mollys,6 tiger bahms, 2 black widow tetra, an ague eater and three neons.
She started out with 5 neons and 2 died quite quicky then the other three developed fin rot (thats what we were told they had) we have been putting in treatment (Anti fungus and fin rot by interpet). they have not been getting better but have not died!!
On sat she got two Danios, on sun one of these died and now the 3 ill neons have died and all the tiger bahms (which are normally really lively) have become very quiet.
We have done a water check and it all seems ok.
Basically asking all fishy experts, do you think we have a problem? or do fish tend to die in groups and does this effect the other fish?
