i keep a jag, jack dempsey, green terror and jewel in the same tank. I got them all at the same time at a very young age/size in order to see how they got along. I also got a true texas, another JD another Jag and a flowerhorn, however...texas was a brute, killed flowerhorn and attack everything so gave it away. the JD i have now killed the other JD, and the Jag i have now killed the other jag. So now thers just the four of them with the occassional dominance asserting but nothing major. The jewels the boss, then the Jag, then the JD then the GT. TBH its trial and error but have found it easiest to adjust when they are stil at a young age. Hiding spaces are important! I wouldnt put a dovii in ther or else ther wouldnt be any other fish
then killed it when i was at work. I was
. Google is your friend. But really any of these specially the dovii, paired with a mate and its pretty much over. GL!!
