Nice setup! I hope to try a saltwater setup soon.
I keep a 55g and a 29g at home and we play with a 130g and 90g at work (all freshwater)
My home tanks are cichlid tanks -- 2 growing Managuensis (Jaguars), some Convicts and a few others. The small tank has 3 little Jags that hopefully grow to be placed in the 130g at work
My Jags breeding shortly after a wholesale gravel change:
And the last time they attempted to breed, they tore up the fake plants constantly hehe:
Fish keeping is a fun hobby
