You fry grow quickly, faster than my Macmasteri.
At 1 month I start to give frozen, crushed flake, live Daphnia and mosquitoes larves and freez dried Tubiflex (works very well) and a lot of BBS.
Thanks macmasteri, remember food is important but so is water changes. Fry need clean water to grow. I am feeding live BBS and finely ground freeze dried black worms.
