It has to be my female Parachromis loiselli. I got her at about 4 1/2" 9 months ago. She grew to 7" in 5 months and then started breeding. It seems like she hasn't grown at all in the last 4 months since she's been breeding.

Probably because at 7" she's pretty close to done growing. Remember that Loisellei are some of the smaller Parachromis species, and of course females are smaller than males. Once a fish reaches sexual maturity, it's growth rate slows substantially. I had a Loisellei that I got at 1 1/2" and it shot to 4" in about a month and a half.

As far as the slowest growing, any number of plecos, raph cats, Jack Dempseys, and of course the clown loach.
