Feeding Corys

So I have 5 x false julii Cory's and 3x orange laser Cory's all about an inch to an inch and a half long at the moment...

I have been putting one corydoras tablet by fish science in the tank every day, they never seem to immediately go for it, more like they will all periodically come across it and snuffle up some of what has broken up then bugger off round the back of the tank again, it usually goes within an hour or so with my tetras taking an interest in it too...

I'm wondering is that enough for the Cory's? I have ordered some vitalis catfish pellets arriving tommorow hoping they might get a bit more enthusiastic about those? Any other food anyone would recommend?

They dont seem to get a look in with the frozen stuff as my rainbows gobble it up so quick, I read maybe trying to syringe it at the bottom can help? That also means sticking my arm right in though haha.

I only just got the extra 5 Cory's on Saturday so just worrying if they have enough! I imagine a bit of the usual food ends up on the bottom as I break up my flakes to real small bits to make sure my tiny rasbora get a look in so I reckon quite alot of little bits get missed too! Dont think many micro pellets get to the bottom with my greedy dwarf rainbows though!

I had been putting the cory tablet at the front to try and encourage them to come out more (and so I could watch them) but maybe I should be less selfish and put it nearer the back if they are happier there. Funny cause the 3 lasers hang out at the front loads more than the 5 juliis and theres more of them they should be more confident right lol
