These guys are around 4-5cm big.
I just have fine grit.
This tank has only been up for a week but i transferred all the water from their old tank into the new one including their filter.
I just have gouramis and BN and corys
I feed them on frozen blood worms, freeze blood worms, frozen brine shrimp, thera +A, freeze dried tubifex and discus tucker and they do eat my corys shrimp pellets.
In probably about a month they will be moving into a bigger tank
