I need a larger cleanup crew, my sand is being covered by all sorts of beneficial and bad algae, I dont like the look of it, so I need larger hermit crabs, about a dozen, and a few brittle sea stars. I can trade a couple poland spring bottles loaded with rotifers, enough to start two cultures or one and a back up. If you want to trade, wait a week for my phyto culture to tank off, and I'll make a whole starter pack for the culture(rotifers and food). I need this guys soon, so please respond.
