Hello , I got my thai silk when he was under an inch November 2015, now it's about a year after that and he's 7 inches, about 4 months ago he got a case of hexamita which I treated and got rid of within 2 months time, just curious now that's he over a year old will he top out at 7 - 8 inches? I give him a variety of food cichlid gold pellets, spiralina pellets, and even 2 cubes of blood worms a day, I'm getting worried he'll never outgrow 7inches.
