I started cycling another 55 gallon aquarium a few days ago. I am doing the shrimp method, I threw 3 large raw shrimp in the tank with the filter going. I am guessing it will take about a month to cycle, does this sound right?
Anyways, my original plan was to put a red belly piranha in there, maybe two or three if they are small juveniles.
Looking around, I was wondering what my other options for aggressive fish might be.
I have found that the following may be interesting options:
Red Belly Piranha
Red Devil Cichlid
I am leaning towards getting a few little Red Bellies, as I have heard they are fun to watch grow and can be pretty aggressive.
Any suggestions? After reading I find that the tank would probably be too small for the Red Devil and Piraya.
