Apistogramma Macmasteri Breeding Behavior?


New Member
So I have a tank for a pair of Macmasteri "Super reds" and it appears like they are starting to mate/court one another. The female has turned into a yellowish/amber color, and occasionally turns into a bright lemony color when in presence of the male. Usually the female will tail slap the male, but it seems like the male is not interested and does nothing. Literally a few minutes later the male tail slaps the female but then now the female is uninterested. This has been going for maybe almost a week now and still no success. But today I noticed that the female is really agressive towards the male everytime she tries to "court" him. It starts the same with the tail slaps, but if the male does not respond she would nip the male agressively, but the male doesn't do anything (not sure if it hurts or not since the male is double the size of the female). Now I'm not sure if they are compatible or not. Mostly the aggression is from the female to the male, but sometimes the male would chase after the female and send them crashing into walls and other objects. The female does not appear to have eggs because she is not guarding any caves. Also when she tries to court the male and enters a cave, the male never follows. Any ideas what the problem is? Or should I just keep waiting to see what happens. I have never bred apistos successfully before so I do not know how long it would usually take for them to lay eggs after courting.

She's yellow, meaning she's ready.

1. Yes, wait it out.
2. Without more information nobody can tell. So please:
- post a picture of the whole tank
- What do you feed? How much?
- Are there tankmates? What and how many?
- What's the temperature?
- What do you do maintenance-wise and what's your schedule?

Do you still have the F1 Ivanacara adoketa “red” from the Rio Icana, interested in getting 2 Pairs.

Do you still have Apistogramma diplotaenia pairs available to sell? Please advise. Thanks.

I'm clueless. If I say something you can safely ignore it.

I see that The Wet Spot Tropical Fish currently has the fire red A. agassizi you are looking for. Here is the link:
I've always had good experiences buying from them on line.
I am Hanzle from Holland and keep apistoos for 40 years. Had my own aquarium shop from 1984 till 1988. Always s great fan from apistoos and hyphessobrycon which is s great combination in a Community Aquarium. Perhaps.....in the near future I start breeding apistoos again. Have a 400 liters Community aquarium for hyphessobrycon wadai and apistogramma biteaniata.
