Bit of a novice fish keeper here but have been taking it slowly and not going too ott with buying fish.
I have a 60L tank which I initially set up 2 yrs ago and had a variety of fish in initially such as balloon bellied mollys, tetras and a pleco. All fish were bought from the fish place in brittas (cannot for the life of me remember the name!)
All was going great for 6+ months and then I got a few guppies from them which were infected with white spot and killed everything other than the pleco. Have gotten the odd fish since but nothing much as other things came up and I didn't have the time to devote to it.
Decided a few weeks ago to start restocking as the plecos were lonely. Got 5 guppies and 5 balloon bellied mollys over a few weeks and now I'm left with only 1 pleco and 4 mollys.
I've tested the water and all my levels are fine. I treated with a tonic but no change to loss of fish. I've done a water change and cleaned the filter but nothing!
Any advice much appreciated!
