There are so many that I have seen not sure if same species or just different variations of the same. And I'm having problems finding info on them. My friend has a pair but their colour and pattern are bland compared to pics I have seen. But need more info before deciding which tank to put them in lol.If you have or know of someone with pls let me know. Jager has one male but I thought a pair might be nice because of their different visual traits. Any info, links or sites to investigate pls let me know.
