what are some of the methods you guys have been using to escape proof your tanks? I've got a couple of ropefish on hold at the lfs and I wanna make sure my tank is escape proof before I pick them up. I was also wondering...I noticed while oogling at the pair in the lfs, that the smaller one bit onto the other ones 'feeler' on his nose...and I'm almost certain it tore it off(I couldn't be certain because the victim went and hid after wards) Is this normal behaviour? I was planning on getting them together but would it be a good idea?
