On the weekend I made the jump, a LFS that I regularly go to I ordered in a delhezi and a gold dust. He said that on his order form they should come in at around the 2"-4" length. While I'm still waiting for my 180 to be built I currently am going to throw them my 46 that has 3 cichlids in it. Will I have to worry about them picking on the bichir? And what sort of cover wound be best for them to have to get comfortable in the new tank?
