Im rather interested in bucktoothed tetras (Exodon paradoxus) and their behaviour. I plan to get a 55 gallon tank for a show tank and was wondering about specifics for these guys. (This tank would be mainly for the tetras) Should the tank be planted or will they destroy it, how big of a school should I buy so they dont kill each other, what bottom feeders are compatible with them, (clown loaches?). Feel free to post anything if you own them too. Also how much should I expect them to run if I find a pet store that actually carries them? Thanks
