So I got my Jag around 6 inches in 125G for a month, last week I introduced a smaller Jags 3 inches and the big one start chased the small one around for like 3 days, last few days they dug up cave and still fight here and there and the big Jag still on the winning side. Yesterday, I came back from work and noticed the big Jag fins and tails got teared a part and body server several missing scales...Now, the small Jag beating on big one like nothing! For years I'm only see same species cichlid that the big one always beat the smaller one all the time but this time is different, the smaller one clearly a winner and claimed the big Jag cave for it own after beat the big one down like nothing. Does anyone see or have similar issue?
