I have a trade in deal with my LFS for my guppies, which I am stoked about since he has a couple of lovely large clown loaches I am craving
But I have to grow them large enough not to swim through the slats in his display tanks and guppies are painfully slow growers.
So what can I powerfeed them with to increase their growth rate??
