green terror

  • We are currently upgrading MFK. thanks! -neo
Yes, to avoid unnecessary carnage, I would put the fish alone in 55 or a 75gal. :D As it grows, it will increasingly become more aggressive.
 
is there anything that can go with them?
 
I just recently got a Green Terror myself. He is about 4in and is in a 110 high with a 12" Oscar and a 4" Red Devil. The red devil harrasses him a lot. I have had him about a week and he won't eat the Hikari Cichlid Gold that I use as a staple for the other 2. I had some beefheart cut up in my freezer (that the other 2 will not eat) that I gave to him today and he seemed to like it.

Anyway, the terror is actually the most timid fish in the tank
 
A lot of fish can go with GTs but a 20 is too small for a single GT let alone anything else. With my GT I have 3 O's, various amounts of Jewels, 2 blue Eyes, 3 Synodontis Eupertus, 2 Plecos, 4 Silver Dollars, 6 Clown Loaches and a Chocolate Gourami.
They get along fine, but my tank is 200 gallons larger then yours, and I think its getting a bit crampt. If I could get rid of the jewels and my brother took back his loaches I would be fine.
 
The thing about green terrors is you never know how aggressive they are going to be until mature. I had one and was the most peacfull fish I ever owned until he reached about two years old. Then I understood why they named them green terrors. But that doesn't mean yours will be that aggressive. Just be prepared for what can happen.
