have a festae, used to be in a tank with about 5 other fish, and decided to eat them.
so removed him and put him in his own bigger tank, and put a couple of bigger fish in there thinking he would calm down, but he ate the bigger fish aswel. so now is in a bigger tank by himself.
festaes are great! i just brought a baby about 1-2" long female
iv got a 6x1x1 with a 1200L hour ehiem 1200L hour power head
its got
wild caught pair convicts 3-4"
pair of blue acaras yellow edge 4"
raindow cichlid 5"
3 red forest jewels 3"
1 red devil 4"
2 salivini cihchlids 1-2"
1 fenestratum about 5"
1 jack dempsy 5-6"
4" sucking catfish
6" tandus catfish
2" convict throw back type thing( its related to convicts)
and a orange/white flower horn
then iv got
2x1.5" tank with a red/blue male flower horn
and a 4x1x1 with a 12" female dovii and 7" male
as far as aggression goes they are off the scale, growing to around 2 foot and with half " teeth, the only thing that iv been able to get the male to live with is the much larger female and even then they still beat each other up time to time.
