black fantail

Question
Hiya,
I am pleased to meet you.
My question is, i have 3 fantail fish, we have not long got this tank, one of the fish we called Leon, after the rock group kings of Leon. he was a happy fella always swimming and eating, seemed very content. now we find that Leon stays at the bottom of the tank, and doesent swim around mad. the other two fantails and three small golfish are all hudderling in a group, is there any explanation for this. I would be grateful for an answer.

Answer
Hi Jilly,
 Do you have a proper filter on the tank?  Also, are you doing regular weekly water changes?  You should be changing 25% of the water once a week, every week to keep your fish happy and healthy.
