Why are my Goldfish not Growing?

[michael]

I have 4 Shubunkins, 1 commet and 3 fancies. My 2½ year old Lionhead is only 2 inches. I feed Repashy gel and krill. The odd time pellets.

I feed two pieces the size of their eye, twice daily.

When I see other fish they are much bigger than mine at this age.

What size tank are they in?  Dimensions?  Filtration?

They are in 36Lx18Wx16H. Two AC 70's

That's too much goldfish for a 40 gallon.  Your fish are probably stunted from the lack of room so that's why they aren't as big as you would like them to be.

These fish are not all in one tank. I have only 4 in my 40g breeder tank
