Feeding Frank The Betta And Indian Glassfish.

Bettas are pigs when it comes to food. They will beg for more every time they see you. They are not hungry, they just like to eat. Ignore him. My betta gets 6 Hikari betta pellets once a day and since I got him on 27 April 2013 and he is still alive, he isn't starving to death 


The 'one eye per fish' is mainly a guideline to stop newcomers to the hobby overfeeding. Now that you have had fish a while, you'll have a better feel for how much they can eat. Add some food and see how long it takes the fish to eat it all. If it is less than two minutes, give them a bit more. Overfeeding is the main problem so work up from less than they can eat in 2 mins. Overfeeding causes fat fish, uneaten food fouling the water and snail population explosions.

As for the fish in your son's room, I would use a sharp knife to shave a mm thickness off the side of a cube, thaw that and feed it to the fish. If they clear it up in less than 2 mins, shave another bit off. After a couple of times, you (he) will get to know how much to cut off. Warn him if he feeds too much, he'll get lots of snails 
Is he only feeding bloodworm and brine shrimp? He needs to feed a bigger variety of food. Since we can't give them all the different types of live food they would have access to in the wild, he needs to add flake or pellets to their diet.

Hmmm, I see the problem. It is usually possible to get fish to eat prepared food, but not always. And it involves not giving them the food they prefer until they give in.
You could try a prepared food with a high meat content. Some of the pellets designed for cichlids might work, though a lot of them are sinking pellets.

You can starve them for several days with no problem. It is quite acceptable to go on holiday for a week and not feed them.
