I think you'll find tons of new behaviours in your bichirs. After keeping mine in a bare bottom tank while it was in quarantine, and moving it into a sand base tank,, i have noticed a bunch if interesting things.

That would be ınteresting. Havent noticed anything different so far tho. What type of differences have you noticed with yours ?
