--aquagiants cichla "mono's" are roughly 4-5 inches
--bigals cicha "temensis" are a little smaller
I keep 3 temensis females, 4 mono 3f/1m and a red eyed occelaris female ..
7f/1m in total, all ranging from 13-20 inches.
they occupy a 440 indoor pond, with a FULL 140 gallon sump..
I Change out 100-120 gallons every 5 days...
The only time I see slight agression is when the male is trying to pick a female to spawn..
my only 2 suggestions would be
1-- have a very large setup in place before purchasing any cichla
2- train them on pellets and do it at a very young age...
I only feed "trout pellets" ..25kg baf for 60 bucks... svaes me a fortune.
-------- CICHLA FOR LIFE-------------
