Nice Pair, Keep a close eye on them, separate if you see any aggression. That male could go from 0 to 60 real quick. I had a big male that bred with managuense in community tank and after she died tried 4 or 5 different dovii females with him he killed them all. I tried eggcrate with holes cut out, separating fish, and eggcrate with slate next to it, he would not fertilize through the egg crate and he would play nice for a little while like they were bonding. In the end he would kill them and quick when i didn't moniter them. it was big size diff. male was 12" through 15" and females were 6"- 9". I have two costa ricans that have paired up for about 2 monthes now, still waiting , m 6" and f 4" . Good luck and nice fish.
