I'm a new owner of two new young goldfishes, got them yesterday and they are at the moment seemingly doing well - but I do have a worry here.
I fed them this morning starting off with pellets. These pellets are quite small, I can put 4 pieces of them in 1 centimeter on my ruler so it should be quite alright for their little mouths(though the pellets expand in water).
One of my fishes are quite aggressive, she darts around much more than my other fish, and she seems to also have a bigger mouth. She's able to keep sucking in the pellet I dropped in even tho sometimes it goes out of her mouth on its own, but always been able to swallows it over time.
However with my other fish, it seems that his mouth is smaller, and when he tries for a flake or a pellet he merely reaches the food and pushes them further away towards the current, and then gives up on even trying to get food in his tummy.
I tried breaking down the flakes, even smashing the pellets into almost invisible to the human eye - but he just won't work harder to eat it. He does swim for it, searches, but goes 'meh' when he fails.
Are the pellets still too big? I mean it seems alright for the female (the aggressive one) but not the male (rather timid to me) and its just a little bigger than its black of its eye. I've also tried soaking the pellets into water first, then squish it a bit so its softer and it sinks a little so he'll have a chance to charge for it - but he doesn't seem to have any 'strength'. He seems to not be able to get floating food..
He's always been a calm fella, even in the bag where I had him he was swimming very slowly and swiftly as if there's not a worry; whereas the other one was 'kissing' the plastic bag's walls and making a lot of movements.
I've broken the flakes into little pieces too, but perhaps not little enough? He goes up to them but fails at catching it with his mouth, goes meh again and gives up on food -.-;
Don't know what's wrong, anyone know? D:
Thanks in advance.
