Hello all.. I'm setting up a 75 gallon all male peacock/hap tank. I've been out of the hobby for about 5 years now, and actually feel like somewhat of a newb again, so I'm looking for some general equipment advice.. Heaters: wattage? Brand? 1 0r 2? Lighting: I bought the marineland 75 setup which came with lighting but from what I've been I'll most likely want to upgrade. Any suggestions? And finally I have a brand new fluval 406... Will this be ok alone? I plan on 12-15 fish ... Any guidance or suggestions is greatly appreciated... Cheers!
