Hi guys .I have a group of 4 pulchra and in feeding them a mixed diet i tend to have bits of live shrimp worms etc left on the bottom of the tank from what they spit out or sometimes miss...looking for a scavenger and thought of maybe putting a panther crab in there to do the job. ..Question is will i end up with a dead crab aswell or do you think it will be ok ?? My tank is running without a heater but averages 22-25c so am i the region for both but also needing ideas for something else if this is just a stupid idea haha
