I have a question on the Syndo cats, Im setting up a 55 african biotope tank ( NOT cichlids, sorry... ) The has a Delhezi Bichir and 2 Leopard Bush Fish... I plan on adding some congo tetras and maybe a African Brown Knife.... now what type of syndo could i fit in there? I dont want something that will get huge and need a upgrade this is a perminent tank so no upgrades. Ive read these guys can be a little mean when some one is in there spot so they should be able to stand up to the bichir right? I dont want it to be nipping and picking at everyone though, so only aggresive when needs to be, other then that ill let you guys help me out on this one.
