thanks a lot for your info and input guys, i have another question though, im planning on building myself a 7'x2'x3' tank(315 gallons) i am originally planning on stocking it with a colony of about 6-7 kigoma frontosa's it will have a overflow sump using a standpipe, and i will throw in another canister filter just to help it out, would motoros be able to live with my fronts that i have? or is it just a mess waiting to happen? also concerned with sand, im planning on using pool filter sand because its cheap and looks nice would that work? and lastly will the motoros be able to live under a strong light i plan on using a really high almost blue light to show off my fronts, or just stick to the marine-glo lights im using now? any help/ input s gladly appreciated, sorry for all the questions i just dont want to jump right into things like this end end up in a huge mess.
