hi, today after much hunting i decided to buy a juwel rekord 96 set-up for the good price (i thought) of £107, the tank is 81 cm x 46 cm x 31 cm which is plenty big enough for me, once i have decided whether i want sand or gravel- or a mix of both- i will then plant up, and add rocks etc, i have been told to use safe-guard with the tap water, will this be all i need to create a good environment for fish, i was thinking of keeping two parrot fish, or something similar. is the tank big enough for some kind of plec aswell?
