Geophagus hybrid?

  • We are currently upgrading MFK. thanks! -neo
Mine did the exact same thing, however the tapojas females never seemed interested in breeding. This caused him to become hyper aggressive toward the tapojas males so had to give him away.
The other issue is red humps are immediate mouth brooders where tapojas are delayed.. So may not work.
Would be a cool experiment though.

Has this been done before. The reason why I ask is because I have noticed my geo steindachneri shaking his mouth at one of my red head topajos.

There are know known accounts of any species in the Geophagus genus hybridizing. Your good.

I'm don't believe these two species can hybridize. The 'steindachneri' is an "immediate" mouthbrooder, laying non adhesive eggs on the sand, and which are fertilized just before the female takes them into her mouth. The 'sp. Redhead Tapajos' is a delayed mouthbrooder, laying adhesive eggs on a firm surface, and not taking the eggs into the mouth until they hatch several days after they are laid. There's a better chance of a 'steindachneri' spawning with an mbuna.

I disagree, in general hybridization takes more into account the genetics side of things, rather than specific spawning occurrences. For example, this: http://www.cichlids.com/pictures/pic/FiremouthNicaragua_Hybrid.html

Nics' eggs are non-adhesive, firemouths' eggs are. It works out nonetheless. XD

Mbunas and Geophagus are rather distant relatives, and really I still haven't come across an african x american hybrid, so yeah, imo gonna have a much higher chance of a stein x Tapajos hybrid than a stein x mbuna.

I think you are correct when you say genetically speaking, the 'steindachneri' and ''sp. Tapajos' could produce viable young. What I was really getting at (having spawned both these species) is how it physically could be accomplished. If the 'steindachneri' were the male, he most likely would not pass over the eggs to fertilize them, since he would expect the female to come to him (at least his vent) with the eggs in her mouth. And mama Tapajos just isn't going to do that. And if the Tapajos were the male, he really wouldn't be able to fertilize the eggs by passing over them since the female 'steindachneri' would have taken the eggs into her mouth. I'm sure it would be comical to see them try, logistically speaking:jaw-dropp
