    Hmmm, females lack rows of dark spots on the body and have a more ‘marbled’ patterning than males according to stuff I’ve been reading today but no idea if that’s correct.

    what have you found about max size?

    The answer is best described as ‘various’.

    yeah thats basically what i have found too – the ones i have are about 5cm SV and 6-7TL

    Apparently these are “4-5 inches” total length. They look it, too…

    The breeders we worked with at Shedd Aquarium were 3.5-4 inches in length.

    nice fish – did the photo supplier mention sexes?

    Yes, female top, male bottom but not sure they were owned by the guy who took the photos.

    Sam, is that TL?

    Edit: others’ opinion on those pics now suggests they are both males.

    Yes, 3.5-4 inches TL. They grow relatively fast. By the end of a year the babies were 2.5-3 inches TL. I’ve since moved from Chicago, but my friend at the aquarium says they only have one left as it murdered it’s brothers and sisters. These fish are mad jumpers as well and I think some where likely lost due to being chased and jumping ship. They really are relentless on each other.

    Good grief, and are both sexes equally aggressive? How are yours with each other Colin?

    Both sexes were aggressive in my experience. One more thing to note is the size of the spawn. Although the buccal cavity looked only slightly distended the one spawn we got at Shedd had 62 fry! This surprised me as they were a fairly good size.

    Thanks Sam. As far as I can gather that spawn at Shedd may represent the only time fry of this species have been raised to adult size in captivity unless anyone knows different?

    I know for a fact American fish breeder Mike Hellwig has bred them. I also believe he raised the fry successfully to adult size.

    Do you know him Sam? I think he might have joined this forum quite recently as I remember validating an email address which corresponds to that name.

    Matt: Vyas used to have 1 huge Ctenops. I think its the one in this link: http://indianaquariumhobbyist.com/communit…pic&t=13000

    My Ctenops fry didn’t make it to adulthood. I have couple more adults brooding right now though.
