Hi everybody, I am thinking of buying a new tank soon to re home my male coral blue dwarf gourami, 5 neons, 4 baby mollies and 2 albino cory catfish who are currently in a 20L tall tank which i know is too small for them! My question is what size would be better for them, a 50L or a 70L? I seen both size tanks at pet domain yesterday, they are the blue planet brand, very nice tanks! I am a bit frightened of getting a bigger tank but i know these little guys need more room. Would a 50L suffice them or should i just bite the bullet and buy the 70L? I am scared but excited at the thought of a nice big tank! Any suggestions or advice would really help me, thank you in advance!
