We are quite new to fish keeping. We bought our tank about 8 months ago. We set up slowly and had no troubles for a while. We have foxgloves, catfish, mollies, guppies and Clown Loaches.
They all seem fine - very active until the next morning when one by one they die! No strange swimming - eating well etc. We have had several lots of guppies, mollies, tetras, and now angel fish who have died - The bottom feeders are the only ones who have survived this whole time - and a baby Molly which was born in the tank! Seems everything that lives from the middle up doesnt live anymore!!
