lol, that is an adult brine shrimp in his mouth, he's the only one of the babies willing to tackle an adult, the rest just go for the newly hatched ones.
I did read through that breeding log., beautiful fishies. I havn't seen many cardinals besides the PJ's and the Bangaii's, since I love their finnage, but those guys rocked!
Sorry to hear only 45 days on them though, "Tiny" there is right at 2 months old in that photo. He's one out of 5 that made it this long. i originaly had 12. They released more but only managed to get 12 out of the display in time. And my second batch I only managed to get out 3. he spit them out earlier than the new tank was ready for em, kinda sucked but my female is already pestering him to spawn again, lol. She's such a little fish nag that way.
I have plenty of grammarus shrimp in my display tank, there a decent sized amphipod so I figure I'll try to get a culture going of just them. The Adult Bangaii's seem to love em when they can catch em. I know my mandarin sure does.
Thanks for the response! i enjoyed the Apogon Breeding log.
