    Apistogramma Macmasteri pair, no breeding behavior?

    A few weeks ago I purchased an attempted macmasteri pair (gold form) from an online site, but to my knowledge I don't think im seeing any breeding behavior? They do 'hang out' and swim around each other often, but I don't see behavior that I have seen in the past from other apistos (female...

    ID of Apistogramma sold as Viejita

    Hi! I got a beautiful new Apisto yesterday sold as Viejita in my LFS. I've read about the Macmasteri vs Viejita ID issue, and I'm starting to suspect that this is in fact a Macmasteri (at least a hybrid?). I think it is a juvenile male. Is it possible to say considering its coloration and fin...

    Opinion about restocking apistos

    I lost the 1 female Macmasteri and 1 the male Agassizii the 40G breeder tank I think might be the Panda Garra that stressed them because he is chasing everyone (he was living on the tank already) so I'm taking him out this weekend. But I have no idea what happened with the male Cacatuoides on...

    How do these 3 month old Macmasteri Redneck look?

    These were born on November 2nd, 2021. They're basically exactly 3 months old. There's currently about 30 in a 20 long. I do multiple feedings a day along with daily 25% water changes. This is my first time breeding macmasteri. Do they look good for their age? They range from about 1.75-2.25 cm.

    Currently I have a pair of Apistogramma Macmasteris and Agassiziis. I want to buy a pair/trio/colony of Trifasciatas. Would you recommend buying mora than 3? Also can I have a trio or a colony of Agassiziis or would it be too many? And if so can any of those Apisto species coexist in the same...

    Water Parameters and Stocking

    Hey all, I’ve been wanting to get some apistos for my 30gal (30” x 12” x 18”). My lfs has some red shoulder macmasteri (sold as viejita) but I’m a bit concerned about my water parameters. Currently I’m dealing with pH 7.5, KH 120 ppm, GH 140 ppm. Would that be an issue for the macmasteri, and...
