egg crate

[Borderjumper]

Does anyone know if this is available in a smaller mesh? I cover both of my tanks with it and I still pick my wrasses up of the floor.

I bought a new little yellow wrasse last week after my existing one went carpet surfing. A week went by and I didnt see the new one so I assumed it died. Last night I was looking in the tank NEXT to the one that I had put the wrasse in.. and there it was! So the little bugger somehow jumped up thru the eggcrate on the frst tank..jumped the 16" space between tanks, and then went down thru the 2nd tanks eggcrate cover. Both of the covers fit very well, so they arent going thru any voids, they are going thru the
1/2 by 1/2 inch mesh. Any ideas? My tanks get too hot to cover with glass. Cheers, Shelley
