3 loaches in a 125g tank? Wow how are those fish going to be able to turn around in such a little tank? They are going to die a painfull early death.
I think youd be ok with 3 in a 125. Better to have a group of atleast 6, but yeah then 125 is going to be getting small once they start getting bigger. I cant say for sure wether it would affect em or not. 55g or 75g, ok yeah they would definatly be stunted after a couple years. I have six right now with the largest around 4". They will soon be going into a bigger tank, a 150. A bigger tank is always better (except for the pocket book) but I cant see myself needing bigger than the 150 unless I had a school of more than 6. Most of the times when I see folks with em in 200+ gallon tanks they have a dozen or more. More power to em, definately a nice setup.
