Hi,i want some advices from your guys again.i used to feed only bloodworm to my fire eel and my other fish.but,as soon i made a variation by fed them with small shrimp and bloodworm,some of my fish stretch rapidly.in just ten or twelve days,my fire eel had grown from 25 to almost 35 cm long and my spotted gar too,from 15 to 20 cm long.but i only have a quite small tank,160 cm x 60cm x 80 cm.and i have a senegal bichir and an aro too.when should i move them to bigger tank?can my tank house them when they are still around 30-50 cm?thanks
