CichlidFish.com - Fish That Think.

Sadly, my Tiger oscar's mate passed away... How do I go about finding a new mate for Teeoh? not sure whether I have the male or female left? Teeoh was carrying the fry in it's mouth if that is a key indicator for anyone? We were unaware that they were spawning...never did see any eggs in the tank. There is a large slate rock for them Not sure if Teeoh mouthed the eggs right away as there is a 8" choc pleco in there also (maybe felt it was a threat to the eggs?) At any rate I saw Teeoh "spit" the fry out but they only survived 2 days....think the pleco got them? They were quite small still at a "wriggle" stage.

All that said...how do I know if Teeoh is mom or dad and how do I go about finding another oscar that would be an appropriate mate? We already have a 12" T.O. in another tank...not sure what sex "Oscar" is either...He was given to me and is said to be approx 7yr old...considerably more developed (thicker) than Teeoh would their size difference create a problem with putting them together?

Thanks for any advice:D

If you can post pictures of them, we might be able to tell. There is no 100% means other than venting, and I don't recomend venting a large Oscar. Head shape and fin size and shape are a couple of the signs. Perhaps stilllearing, or Mark or cichlidfish might be able to hazard a guess as well.

Well, venting is the way to go here -- if you are very patient, you can sit next to the aquarium and wait for Teeoh to flash you.

Fins, body and head shape, and size are only accurate to determine gender when you are absolutely certain that Oscars are raised with the same water conditions, disease history, and food. So, these methods are not accurate when 1.) you are trying to sex a single specimen, and 2.) you don't know the history of the Oscars in question.

Oscars are not mouthbrooders, so it's interesting that Teeoh was keeping fry in his/her mouth. Occasionally (not always) Oscars eat their offspring, maybe this is what was happening --

Male

Female -- These pics are from Stilllearnin I believe, they are in the galleries here at CichlidFISH

Thanks for the advice...I have two oscars at this point in seperate tanks...Is size difference as important when putting them together if they are opposite genders? I was just spending a little time staring into the tank and have discovered that at least 2 fry have survived at this point not entirely sure had to tell if I am seeing the same one over and over? LOL...I was able to net one into a breeding net is this a wise way to try to raise it up? I removed the pleco to other tank to give the fry a little better chance...Should I remove the adult oscar as well? Any more help would be really appreciated

Oscars vary so much from specimen to specimen that it's impossible to say. Go ahead and try it, but be ready to seperate them again if it gets too rough.

Should I remove the adult oscar as well?

Again, depends on the particular Oscar. Might be a good idea to be on the safe side --
