wow, very thorough info, bro!
well, guessing i didnt make it clear, i want a "bottom cleaner" who will eat those surplus food left by my asian arowana, not those algae eaters (pleco) that i already have.
i am now keeping a pair of Synodontis eupterus as bottom cleaners, but they cant grow big enough ...

planning to add another bottom cleaner, Oxydoras niger VS Megalodoras irwini :cry: , which one is better at doing that cleaning work?
any experience/info would be appreciated!! :mrgreen: :thumbsup:
