Hi there, I currently have a 240 litre tank with sum tetras and 5 discus. They are about 4inches now, could anyone tell me wot size they grow to and wot size of tank I would need in future?
Maybe if u can let us know what type of tetras they are?! The discus should be fine in ur tank. Likely with the tetras as well. Any other fish in the tank?
what are your tank dimensions?
some types of tetras will nip fins of slow fish, and discus are slow. depending on the type sometimes keeping larger numbers of tetras will reduce their nipping.
