Is it because she is fat or is this the natural shape? What I noticed about plecos (at least bristlenoses) are that larger they grow, they turn "fatter"! They looked prety slim when they were 1 inch, and more they grew, they left me with the impression that they are getting fatter (or flatter). My largest female is about 3 inches and she is clearly the widest of all of them by far.samthefishman said:I got 2 females, 1 just layed eggs, the other one is HUGE! its gonna burst soon. I am worried maybe something is going wrong. She is so fat she needs to lay then otherwise shes gonna explode!
