I am looking for ideas to cover my brain and fungia plate during feeding. My Wrasse and Tang pick all the food out of them before they get a chance to consume and food when direct feeding. I bought a tupperware bowl and put a holes in it but it still floats. I considered weighting with a rock on top but then how would I retrieve it without putting my arm in the tank. It is 27" deep so that is close to the arm pit. LOL
Pics appreciatied
