I recently posted a thread asking on the legality of keeping a wimple piranha in Colorado without a permit. Since it appears I can, I was thinking of getting one. Would it be okay in a 20g long? If I had to, I could get a bigger tank, but I cannot get a tank larger than 30" long due to space. The tank was originally for a T. suvattii (a puffer), but the shop that said they had some didn't. I am now at a loss as to what to put in here. The filtration is an Ehiem 2213.
Thanks,
Ryan
