I have a 225 5x3x2 (wide) and I had SA/CA cichlids in there. I got bored very quickly of always having beaten up or killed fish, not being able to add any new fish for fear of them being killed etc. so I went to predatory tank. I have less agressive predators, stock is...
Chocolate cichlid
17" pleco
3 tinfoils
2 ornate bichirs
1 delhezi bichir
1 short body sen
1 indo datnoid
1 clown knife
1 giant gourami
1 pink tailed chalceus
1 upside down catfish
So a good selection of large predatory fish and everyone gets along really well. enjoy this so much more than my cichlid tank.
And seriously, if you want a nice big tank like that with 2 fish that will spend most of their time hiding, grow extremely slowly, and onyl look their best when they are breeding/ beating the **** out of eachother then sure go for it.
