What is this? Thanks for looking

planaria flatworm

What do they eat?

 

[Sisterlimonpot]

phyto, rotifers of the like. They're harmless but can reach plague proportions if left unchecked. The problem is if there is a mass die off they will emit a toxin that can cause lots of problems for a reef tank. People either treat the tank with flatworm exit (or something similar) to kill them off, or get a predator like a couple wrasses to keep them at bay.

Something worth considering...

These can be nuisance as they regenerate quickly, have no lungs and therefore are survivors and repair themselves when cut into pieces. They food on oxygen and some slime.

I would not get a second six line. The one you have should keep the numbers down. Two six line in one tank will not turn out well.
