So for the past 4-5 hours since doing tank cleanings on 3 of the 5 tanks running I have watched some extreme cichlid aggression. I decided i needed to move some fish around from other tanks. I put my female convict full grown, 5-6 inch geo, 4 inch pike, and a 4 inch jag i just got into my 75 with my grammodes to see if it would decrease his aggression. I added new decor i got for xmas to wipe the slate clean territory wise. In about 30 minutes after the grammodes did some swimming around they turned crazy. The female chases all the fish except the male grammodes. The male grammodes has turned into a complete psycho. He chases everyone equally and has the energy to never stop. The jag was bought because i thought he/she would be able to compete for top fish but this male grammodes wont have it. I had to remove the convict before any extreme damage was done. The female turned dark and hasnt lightened up in color while the male got darker markings than usual and his fins turned a deep red color and his war on the other fish began. The only fish i can compare him to would be the first jag i had around 2005. He was a monster at 13 inches and wasnt afraid of a thing. He was housed with a mala wolf fish with a divider and the jag busted it down and ripped the mala's throat out while i was at work. I sold him shortly after that. This grammodes is less than half his size and is comparable to my old jag. I see no way of keeping him wiht another fish unless i growout the jag a lil more
