2 different groupers. the whiter looking one in the 47 tall is a cherry grouper-also sold as a veil tail i believe. the other is (deep red with blue spots) a miniatus, def. my fav grouper by far. colors are simply amazing. My setups include a 120,90 & 25 system, Double stack 55's system with a third 55 sump. a 47 tall, and my newest addition a 197 gal. with coral cat shark pair. i also have a 20 and 10. I started with one 55 a year and a half ago and now my stock includes.
Miniatus grouper, cherry grouper, panther grouper x3, yellow tang x3, desjardini tang, 2 clowns, X-mas tree wrasse, niger trigger x2, picasso triggerx2, figii blue spot puffer, stars and stripes puffer, snowflake morey x2, copperband buterfly x2, chocolate chip stars x3, black volitan lions x2, cream angel, red emperor snapper, green mantis shrimp, 2 coral cat sharks, and one of my favorites an undulated trigger.
I think salt is easier to maintain by leaps and bounds of freshwater but my salties are alot smaller than any other fish ive ever kept. Initial set up is more $$ than fresh but worth it in the end. I have 28 tanks running at once so its nice not to worry about my salt tanks very often.
