Yes But there is a ratio and size requierments , If your Piranha are SMALL 1.5"
or so then make sher you have lots more Piranha than EXO's , The EXO's
are scale eaters and are Very Very Much faster than a Piranha this falls
under the ratio , Say U have 1----1.5" Piranha and 3 EXO's Good Buy little
Piranha the end . Know if U have a tank of 6 to 12 inch Piranha and lots
of room I would keep 2 EXO's to one Piranha and at this the EXO's will
still eat the scales off the piranha but its not that big of deal , Bigger
scale more of a meal for the EXO's and you can help the EXO's to not
eat there scales by feeding them flake food works good .
Expect to loose a EXO here and there .
