Thank you for the tips.
They are legitimate N class endlers, he spent almost $100 on 10 of them. I have 3 tanks at the moment, one for the pure endlers, another which will be my breeding tank, and my community tank (all in separate rooms). I have a few fancy guppies and at least 2 K
class endlers that are absolutely gorgeous, and I really want more of them!
I do plan on keeping the one tank as a pure endler tank. I really love these little endlers, so much energy and very playful.
I guess I will need to keep checking on them, I haven't noticed any color yet, but some do seem a little more plump than the others (still really hard to tell), and I am guessing those will be the females.
