I went to petsathome to buy some small fish for a small 30L cube tank. I asked for some advice about fish points. 30L / 2 = 15 fish points. I pointed at some random fish and asked if they would be suitable for a new tank, yes was the answer, and said I could have 3 fish in the tank. So I walked away with 3 angel fish. Only afterwards did I research this, when they started nipping, did I realise 3 angel fish in a 30 litre tank is probably not a good idea. Unless these are a different breed of mini angel? Could be possible I guess? Seems a bit odd. Angel fish are listed as 4 fish points on the website as well as in the shop. Any thoughts?
