hi, i have a 4 inch albino bichir and a 4.5 inch delhezi bichir in my 29 gallon tank. my mom doesn't like that my bichirs are lazy 'bottom feeder" and she is urging me to gets some more "stunning" fish that can be easily seen. what fish can be kept with my bichirs. will upgrade my tank to a 72 gal but i want to put a piranha in it instead. It would be awesome for you guys to give me some some "exotic", eyecatching or a beautiful fish that can cohab with by bichir in my 29 gal. no fin nippers or very risky aggresive fish please!!!!
Thanks

Thanks
