Sexing, if possible?
 
I know the gender of -most- of my tank, but 2 seem to be hovering on both genders, and was hoping for some outside advice...From experts. Lol.


This one is 3", give or take. S/he should be at full color, but still looks like a juvenile. I'm not 100% sure what s/he is, besides pure bred. My LFS makes sure. We do suspects/he is a Psudotropheus Flavus, but as in all things, there's some leeway there. S/he has colored up, has some limited stripes, but remains grey/pale yellow even when colored. There are no egg spots to speak of, and has no defining anal fins that are obviously gender-assigned. S/he has also displayed to females, but has been displayed too, so....

Here are some shots:

And, my (I think) Crabro (If S/he isn't a Crabro, let me know):

S/he has never been fully black, and is 3.5-4". Thank you!

Top one is a Pseudotropheus flavus female. Females stay that color with light bars showing.

Bottom is a Pseudotropheus crabro.

You have some extremely aggressive fish there and a small tank, this may cause problems.
The tank is also too small to house these fish long term as a lot of them are going to get to 6-8".

Like a lot of Cichlids it is nearly impossible to sex them without venting them. Venting is extremely stressful to the fish as it involves taking the fish in a net an examining the anal area to check the sex organs. The fish cannot be out of the water for more than a minute otherwise damage can occur to its gills.

I refuse to vent. I like to know what they are, just so I can watch them for mouthbrooding to either get them out or provide extra hidey spots.


Believe it or not, I've never ever had a problem with aggression. My dominant male Hongi who is four and a half inches long and an inch and a half tall, the second biggest boy in the tank, does assert himself, but the others just obey him and I've never ever had a mouth-cling fight or anything. They squabble over food and the rare cave, but that's normal. I've seen nothing that would suggest that they would be killing each other. They're all happy as Cichlids are. I've even seen the larger ones sticking up for the non cichlids and telling the babies off for trying to peck at the SAE or Clown Pleco.

Even my Jewel Cichlid (adopted "her" from a friend whose other cichlids were killing it. I told her its likely going to happen in my tank too but then she didn't have too see it) and I can move "her" out to the goldfish tank where she was before (believe it or not, the goldfish were killing her). There's been no injuries, no peck marks, no frayed fins, no nothing like that. Just the usual showy fin flaring and rapid fluttering, lol. In fact, over in my goldfish tank, my little one inch molly is the most aggressive fish int he house! Lol. I named him Vader.

If you do not want to vent them then the only way to tell will be when you have a female holding with a very big bulge in her throat.

:thumbsup: to no aggression. :-)

This may be a stupid question. I know some Cichlids should be kept with one male to several females but how do you tell their sex when buying them?

Tazman 05-17-2012 08:32 PM

Many buy extra juveniles and wait until it is possible to tell the sex apart by venting or in the case of diamorphic (not same color male/female) see the difference.

Some fish stores have the knowledge to know how to vent them or have sometimes separated them already.

I think I have a strawberry that is carrying, she has not eaten in over a week and her jaw, rightin front of her gills are pretty brused looking. She has a spot she hangs out in the tank. How long before she would spit them out if she is indeed carrying fry?

Tazman 05-17-2012 08:37 PM

18-24 days is usually about right, it is safe to stripe her of the fry at 18 days minimum as the fry will have developed enough to not have egg sacks. If you stripe her and the fry are not developed and still have egg sacks, stop IMMEDIATELY unless you have a way of dealing with immature fry, which take a lot of care.

Usually you will see her acting like she is chewing gun once she is nearly ready to spit as the fry are free swimming in her bucchal cavity in her throat.

Egrant 05-17-2012 08:41 PM

Thanks Taz, it does seem like she is "breathin"' evily opening and closeing her mouth a whole lot.

Thank you Tazman.
