so on tuesday or wednesday i can't quite remember i bought 2 new goldfish and put them in a large tank with my other 3. one of the new ones was floating with its head down bit it was bloated and that went away then 1 by 1 all my fish started to go behind the filter yesterday the last one did well apart from 1 so i took that one out and put it in a different tank because i thought it may be bullying them. immediately all the fish came out so i was like problem solved. yeah i was wrong they all went back and hid next to the filter. when i feed them they come alive and swim around and have some food then just go back to the filter and do nothing. i don't know whats wrong please help.
thank you
hey,
I have 40 litres of water in but could fit 50.
the four fish that are currently in there are: one is about 3 inches long and is a chunnky fish not a thin one, then i have one about 2.5 ins long but only about 1cm wide then i have two small fish that are about 1.5 ins long and about 1 ins high.
