What gender is this green terror??? (Sry for bad pics)

  • We are currently upgrading MFK. thanks! -neo
At a young age all Andinoacara are difficult to sex, even with the most clear photos.
You will need to post a very clear broadside to enable anyone to give an accurate gender ID.
At minimum, Something like these shots below
View attachment 1529862
The one above is a male, note the dorsal fin point extends as far out as the caudal (sometimes farther with maturity).
Whereas the females dorsal extends only half way into the caudal area
View attachment 1529863.
Below another shot of a male, showing that extension, but also note a lack of black melanin throughout the body
View attachment 1529864

Above and below a female, slightly more melanin, the dorsal fin shorter, and notice the more prominent irrideceent blue spangling on the gill plate, and jaw area
View attachment 1529866
below a male in the foreground, note the longer dorsal"and" extension of the anal fin
View attachment 1529867
I will also note the males are more streamlined, a bit less boxy shaped than females, hard to see if they are not together in the same tank.
And to throw in more confusion, during fry care, the males melanin also intensifies.
The male in the photos above is about 7", female 5" (another indicator, males are generally larger) at the same age.
Trying to determine gender and 1 or 2" is impossible, because these traits are not developed or visible.

I find the best way to get a compatible pair, is to buy a group of 6 to 8, and allow the group dynamic to play out

ok thank you so much, I’ll probably be picking the little dude up today and I will grab some pictures of him. Sadly I only have enough room for just him and he is the only one in the store anyways. He will be in my American cichlid and he will also have another friendly eba

What’s in the tank already? How large is the tank?
Often similar species won’t tolerate another of the same genus/species.

I have a temporary 16 gallon tank for about another month until I can get a new tank (either a 40g or 55g) right now their is x2 male convicts ( yellow and pink), a female electric blue acara, a female firemouth, a female convict and a polar blue parrot cichlid. I also have 5 gaint danios as a dither fish and for my cleanup crew I have a female albino bristle nose pleco and a female flying flying fox. I have a zero tolerance for high aggression and bullies, so I dont have to worry about that and the new tank will have spider wood, clay pots and anubuis/java fern. All my fish get along perfectly fine, the tank boss ( a 3 1/2 in yellow convict ) is still pretty young but he is a gentle “giant” I would say or his species size

In a 16 gallon I’m surprised nobody has killed each other - and that won’t change in a 55 with that mix of cichlids.

They are all very young, a 16 gallon should be fine for 1 month. What is the problems with the cichlids?

I thought convicts and firemouths were good, and the firemouth is female so it won’t get too big. Also the polar blue parrot cichlid and acara can hold their own
 
Most Cichlids don’t like company - especially conspecifics, with the exception of a receptive mate.
There are 4 convicts in that tank (the two male described, the female, and the polar blue which could be a male or female). A pair of convicts is enough cichlids for a 55, they again don’t like company.
The acara and firemouth both add to that bioload/aggression load. Firemouths are pretty tricky to sex if I’m not mistaken, and there are reports of 10 inch ones on here. A female can easily get 6+ inches.

The firemouth size isn’t a concern she was the smallest one out of the batch and is like a goldfish, she’s never attacked anyone. Same with the acara. The thing I completely agree with you on is the convicts, their breeding is to much aggression. I’m in a situation where I’m not able to seperate the pair. (Green convict and normal female) the female is territorial, but sadly I cannot seperate them.
 
I put a dozen Acara in my 180, at about 1 year, the alpha male killed all other males, and some non-receptive females.
He allowed only 3 females with him in that size tank.

16 gallons is no more than a puddle for cichlids. I wouldn't put anything bigger than guppies in that size tank.

The fish was dead when I showed up to buy him. Again the tank is temporary for a month. The fish are still young and around 2-3 in. Also the mostly likely case is my firemouth becomes the tank boss. It was the smallest out of its siblings and it’s barley aggressive.
