Is this a female apisto cacatouides?

Two years old, I thought it was a male for the longest time but the dorsal fin is the same size as the other plain female I have. The caudel fun has no black mark at the base though, so I'm confused.

How old is the fish and how big is it?

Looks like a young male due to the colour in the fins, however it shouldn't have a round tail. Round tail normally means a female. It could have a deformed tail and then it's a male.

That is a weird fish. It's not cacatuoides. Could it be a hybrid?

it's an interesting looking fish isn't it

 

[GaryE]

It has a njisseni/panduro shaped tail, a low dorsal with linebred cacatuoides set of markings, and attributes of both sexes. I've had quite a few intersex fish show up in Pelvicachromis over the years, but that one looks inter-sex and inter-species. Whatever it is, it's a cool looking beast.

Ty, it is cool. It is full grown by now, I've had it for 2 years. I will try to get a better picture later. But it could be a hybrid hmm

If it's 2 years old it's definitely sexually mature.

A lot of female Apistogrammas look the same so it is possible someone crossed them either deliberately or accidentally and you got the offspring.

Does it every display to other fish?

 

[jonny5]

It never displays in courting, only in bullying. Side by side, the one the right is a little washed out due to sand color. But both of these came from the same store tank 2 years ago

 

[jonny5]

Side by side comparison. I am going to find a male apisto cockatoo, see who he tried to breed with lol

The fish on the right has the wrong body colour for a female A. cacatuoides. It should be a lot more yellow rather than cream. However, the fins are correct for a female.
Has it ever looked yellow?

-----------------

You have blue green algae on the sand. It loves dry food, low oxygen levels, calm water and nutrients. If it gets worse it can affect the fish that live near the bottom. Regular gravel cleaning and big water changes usually help get rid of it.
