I ordered 6 from Jeff in 2009. 1 female killed all the rest within days. Then I purchased a 2.5-3" pair from Ira. They were fry from GMFISHNUTs pair that were brought in from Mexico by JoeFatFish.
This small pair killed 30+ of its fry brothers and sisters and formed a tight bond and I grew them out and had about 10+ spawns from them. Male ended up being around 9" , female 5".
I kept them as the main fish in a 265g with a neet, HRP, convict, pictus and 4 clown loaches. Never had any problems with them that I can think of. Theyd spawn and take 1/3 of the tank but thats about it. Ive had WAY worse trouble from spawning convicts...WAY WORSE.
They were beautiful and interesting, but not very interactive/ owner responsive. They didnt hide a lot, but they werent at the tank front like my current jag or old trimac.
I shipped them to a friend in NJ and within a month the male killed the female.
