I am having the same issue... rtc with an aro and a gator gar? I keep the rtc well fed so he won't eat any thing else.
wouldn't trust a rtc to keep his mouth off smaller fish just because of that logic.
22" rtc and 15" aro with a pair of 7" oscars in main tank. 9" gator gar and 4 - 5"-7" cats (rtc,tsn, 2x rtc/tsn hybrid) in grow out tank.
gator gar can easily eat your other cats...now and in the near future...
A 7" oscar looks tiny next to a large rtc. the aro is fast enough to get away from the rtc but the gar is not. I can say that the rtc only come to the surface when he sees me but I don't know if putting the gar in is a good idea! I will probably put in the gar in a few months when I need the grow out tank to breed g severums...
not really a very good reason to introduce the gar into the tank. it's a poor combo as i've already mentioned...if you really have no where eles to add the gator, give it up for adoption. if you didn't have facilities that meet the requirement to keep a gator gar long-term, or at least have a contingency plan, you really should have thought twice before getting such a demanding fish.
we share a common dilemna but I currently own the mix of fish in question...
