I don't see why your LFS won't take the peacock gudgeons. I thought they're pretty rare?
Yes, the tank is overstocked when you consider the fry. If you don't feed them, I doubt many of them will survive. Are they already free swimming? Have their yolk sacs disappeared? If the answer's yes to either of them, then they are ready to be fed.
From my experience, it's easiest to catch fry using a turkey baster. The parents might not be happy about it, but it's the most efficient way I've learned to do it. It's also easiest to do it while their wrigglers since they wont dart away or try to avoid you.
You can try feeding them hikari first bites if you don't want it to be time intensive. If you want to be gungho about it, you can feed them newly hatched brine shrimp. That comes with it's own hassles, however.
Thank you for the quick answer.
I bought these gudgeons at the LFS round the corner, this fall.I had seen them there ,didn't know what they were at the time ,and I already had shrimp in my tank.I thought they were some sort of killifish so I had doubts about buying them as shrimp roommates.I asked the guy what species they were and he showed me a photo of Apyosemion Gardneri.I had doubts about that too ,cause the mouth placement of Gardneri was not the same as the Peacock gudgeons.]
I don't blame the guys at the store for not knowing ,as it's rather a pet-shop ,not a fish-only store ,they have all sorts of creatures ,from pythons to parrots to tarantulas and chinchillas to take care of,they are all doing a great job ,and they are nice and patient to their customers.
I didn't buy them at that time ,still believing they were some sort of kili ,until one day ,I said what the hell ,and bought them.I posted a pic on this forum and it was then I got the right answer :Peacock Gudgeon
As I also found out they are kinda rare ,I thought they had no chance of reproducing in my tank ,and somehow hoped they would keep my shrimp from overtaking the tank ,eating the babies ,yet shrimp numbers still increased.
The fry are a 2 maybe 3 days old ,all I have as fish food are some flakes and frozen bloodworms.Should I already try feeding them finely grinded flakes?
