U feed them well with fresh vegetable so why would they wanna chomp down on cheap vegies ??? I have crypts and anubias in the tank but my magnum just leaves them alone...so much food and green algae to chew on. Otos are good too but they only chew brown algae.

They do eat algae when they get desperate for greens. If u looking for an algae eater, hmmm...try getting a sturisoma instead...good hardworking fella but not too effective though...gets the job done. If u are not certain which type of pleco to get, do run a search from planetcatfish.com and a pictorial site at transfish.de for confirmation of genus.

Well for me, a tank tat size, i would keep...PLECOS
Big huge Pseudacanthicus or Panaques Nasty pooping machines though

Hatchet fish hmmm. Then u shud cover the tank because they can really fly. I
