My established FWLR tank has recently been invaded by dozens of tiny eight legged critters, which also have small antennae. What are they and do I need to get rid of them? Thanks!!
Think yourself (and your fish) lucky. How big, and what's in, the tank. There are a variety of fish that will only eat pods - maybe you're in the lucky position of being able to keep them! (Mandarins for example).
