Redbelly Piranha in a 55?

  • We are currently upgrading MFK. thanks! -neo
3 Natt's in a 55g are alright, but once they start getting past 8 or 9in, you might want to upgrade to keep aggression the same as when they where juvi's (if you got them as juvis)
 
I got a caribe and a piraya in a 55 right now. Both are only around 4-5 inches though and upgrading after the summer.
The caribe is pretty territorial and bullies the piraya and its a job keeping the nitrates under 20 ppms. It can be done temporarily though, you can probably get a year.
