Scavengers
 

What if any type of scavenger can I put in a 29g tank with 4 juvenile African's (yellow lab, female kenyi, red zebra, ___)? I don't know what the last one is.. He/she is purple w/yellow fins and can go from deep purple color to violet on a dime.

I have a small red crab in there now, but he hides 24/7 & I question what if any scavenging he is actually doing.

I know I am a bit limited by the tank size, but I'd really like something to help keep things in order at the bottom of the tank if at all possible.

there are a type of catfish you can throw in there that are from Africa. search upside down catfish as a starting point. these were recommended to me when i was trying to find out the same thing.
