So Bad Cat... my oldest RTC is about 26 inches long now. I feed him by hand... mainly fish, shrimp, chicken. I only feed him about every 4 to 5 days. Not large meals either. He was 3/4 of an inch long when I first picked him up. It has been nearly 2 and a half years now. I have 2 others, they are growing fast but hate each other. I had a TSN hybrid with Bad Cat but "Black Hole" turned into a bully. Tries to kill and eat everything. No rhyme or reason to it. Including air stones.
So... the hybrid lives by himself in a 125 gallon tank. Quarantine is what I call it. He is quite large, but has no issue turning around. Bad Cat on the other hand lives in a 300 gallon trough. Is quite happy and comes up to greet me daily. Acts different if hungry though. Lives with a few oscars.... an irridenent shark that's about 24 inches long and now a small pleco and Black shark. The black shark was supposed to be food for Bad Cat... well, they are buddies. The black shark will sleep on top of Bad Cat... crazy...
Last night, Bad Cat killed the large pleco that was living with him. Large means 20 inches.... they had been together for over a year. So perhaps Bad Cat is in a killing mood again. This has been the signal of another growth spurt in the past.
Once Bad Cat out grows this 300, I am getting a 1200 gallon tank. Add another Fluval FX6 to the system and set up a 55 gallon wet dry filter that will over flow back into the tank. Hoping that is in another year. Hahhahaa
