My 24 yr. old son has been harrassing not G2 but the worm population in G2's tank. He asked me to get feedback on whethor it's healthy for the tank to have possably hundreds of worms, who I consider my cleanup crew residing quite happily with G2. I told him I would post and get opinions on whether my opinion that the worms are good and help maintain the tank are correct! And in Elmers tank, an old octo tank originally, I think the Bird Wrasse has been digging for them. I really haven't noticed that tanks population of worms at all since Elmer resides there. What does everyone think?
