hey johnny awesome man that's so exciting the first time you see them pair up and then it's even better when you get your own babies. they're wicked fish to have breed too. both red eyes, interesting bright pattern, and most importantly both pigeon (as a turq/pigeon cross such as a pair on T* at the mo = ugly hugley peppered babies).
they don't look too stunted but if breeding at that size it is likely they haven't grown to their full potential that they could have. doesn't matter tho. if you raise the fry on daily water changes/great diet they can easily superceed the size of their parents.
go for gold with raising them in planted tank if you want the only thing is that as the parents are pigeon bloods the fry will likely get lost trying to find them cuz they'll go for anything dark. when i bred mine i had nothing in the tank even had to take out the black filter sponges around the key time of them going from wriggling to free swimming so they could find the parents.
i do have a big display tank i could put the 2 other ones in if you're stuck but it's at my friend's place so i just can't keep an eye on them everyday is the only thing. that small tank would be ok if doin daily or every other day large wcs.
