I bought a couple of small specimens about one and a half month ago. Today i found some fry in my tank. The parents are less than 4 inch body lenght. Sorry for the bad pictures.

Better picture of one of the parents

Congratulations! Good for you. 4" long, about 10cm. Is that SL or TL?

Cheers, Eric

Not even 4 inch total lenght

Might your fish be misidentified? Maybe you have a species smaller than . For example, reaches only 15cm SL.

That said, some fish breed at a very small size if well cared for. I have rainbow cichlids that started breeding at 3cm. Unbelievable.

It might be, I'm trying to get hold of the pictures of the parents of these ones.

Quite a while ago I had a few Sturisomatichthys sp, of the Dutch genepool, and Sidguppy, who used to be active on this forum came along. Wow he said, those S panamensis are huge. Huge they were, around 20 cm (8 inches).

But, I did not believe them to be S panamensae, I always believed they just happened to look a lot like S panamensae.

The problem with these fish is, the genepool of them is quite divers, but regardless what they look like - they are the same hybrid

Hi @Bas Pels,

I am unclear on your intent. Are you saying that you believe these fish are interspecific hybrids?

Cheers, Eric

I don't know about these fish, but unless the fishes were sold as wild caught, or decendents from wild caught ones, I would assume they descended from the genepool available in Norway.

I do know that the genepool available in the Netherlands is most likely a mixture of several species, but that is all I know. Norway could have their own genepool.

What I intended to say is - whether the fishes do look like S panamensae or not, that does only have a meaning in case one knows about the parents. If this is not known, please assume they just happen to look as they do.

Thanks for the explanation. I understand now.

Cheers, Eric
