I'm new here and to the hobby.
Its now almost 2 months since I bought a small 8 liter fish bowl for my then 2 gold fish, 1 beta $ 1 black moor. I added two more fish to the mix, 1 lion head & 1 angel fish.
Unfortunately they have began dieing!!!
I woke up one morning and 1 gold fish had died. then the angel fish, then the other gold fish jumped out at night and was seen the following morning. this morning the black moor!
