Hi, I recently purchase a group of baby congo tetras they are just barely and inch right now....just wonderin how fast do they grow??? I feed them twice a day with colorbits, sprulina flakes, nls, brineshrimp, bloodworms....the reason I bought them is that they were cheaper than buying the adults......right now from a far they look like feeder guppies, but if you look closely you could see a little bit of colours.....just can't wait till they grow.......does anybody here raised them before??? thanks...
