Female apisto caucatoides??

[AquaAggie]

So I have two apistogramma cacautoides. I think I have a male and a female. I have had the male for 7 months and was sold to me as a super red and the presumed female for about 4-5 months. She has not grown a whole lot is about 1/3 the size of the male. They don’t pay much attention to each other. I even built a hole cave specifically for them. Is she really a female. How big do the females get?

 

sorry taking pictures of fish is hard

Pretty tank! Nice male. Hmm . . . well, the little one might be a female. If you've never seen her turn yellow and "court him" by bending and dancing in front of him, it might be that you've got a sneaker-male. She'll do that about once per month is she's mature and doing well. 

Off hand, is your smaller one (presumed female) always that thin? Does she have white stringy poop ever? Ours ended dying of parasites. It was a slow wasting away . . . wish we had known more about diagnosing that, and treating them.

For comparison with your female, here's our confirmed male and female from awhile ago:

Thanks for the compliment. Also your tanks are great and the video was helpful. Obviously the “female” should be bigger. I’ve never really thought her skinny but like I said she doesn’t seem to be growing all that fast. Since she has more of the yellow on her fins I though she was female and since she wasn’t getting male markings either. I’ll look closer at her about the skinny part. I know everyone is always asking about poop and I know fish poop a lot. I’ve seen my filter sponges when I clean them. And when i was kid I remember always seeing those long poops hanging out of our fish, but in this tank I never see them hanging out of fish. She definitely eats well whenever I feed and I quarantine with the MED trio for all my fish. I have also started just doing a full treatment with paracleanse for just the concern you raised. Maybe I’ll try and catch her and treat her anyways. Couldn’t hurt.  I saved one khuli loach that way so far. Thanks again.
