Hi all, I am just looking for a much information as poss about them,I am thinking of getting 4-5. Tank size is 4ftx18"X12" I know this is a bit tight but i am looking in to a bigger tank.I am thinking med size as i would not be in enough to feed and clean smaller ones due to work, But 2-3 times feeding and water change would not be a prob.Just trying to find out as much as poss before getting them. Also i have kept trop fish for 3 years. Thanks
ps tank size is about 37G uk
