Sounds okay, but try to get some veggies in there as well... A varied diet is key. Buy some hikari cichlid pellets... I use Bio-gold + for my CA's, but and of the hikari cichlid pellets will work. Use the pellets as a staple and a few times a week give them the frozen shrimp and prawns, and mix in some brocolli flouretts as well.
And I guess I got a super vieja... My uncle had a fenestratum in a 180 which grew an inch a month untill about 10", then slowed down. I heard reganis were the same
