So I bought the Aqua One 620 (90L) three weeks ago, and foolishly stocked it with African Cichlids. (Malawi Mbuna) .
After further research, I have found that 90L tanks are just not big enough for the African Cichlids, So I have purchased a 185Litre tank on trademe. http://www.trademe.co.nz/Browse/Listing ... =649099533
As far as filters go, I need one that hangs down (not under the gravel) as the Mbuna dig around and could uncover the plastic thingy.
Also for the 185 Litre tank, is a 200 watt heater sufficient enough to keep a constant 25/26C temperature?
I am excited for your responses! Will upload a pick when it is all done... over a couple of weeks.... finances a haha
