I see you're discovering the world of rabbits, I mean live bearers. Fun! And welcome to TFK!
You can click on the shaded names of fish and plants to read more about them. You can also use the "Tropical Fish Profiles" link in the dark blue navigation bar at the top of the page. You can see that the Clown Loach gets very large (12"-16"), needs to be in a group of at least 5, and needs at least a 6 foot tank (because of his size, his need for a shoal, and his activity level). A Clown Loach grows very quickly. Every second he spends in these tight quarters destroys his health and shortens his life.
A good way to get a more accurate feeding amount, especially for just a few fry, is to pulvarize the food to the desired sized bits in a baggie, wet a toothpick in tank water, dip the wet toothpick into the powdered food, and then dip the toothpick into the breeder just enough to deliver a small amount of food. Be sure to clean the toothpick in hot water and dry between uses.
The suggestion of baiting for snails from Tazman is a good one, if ongoing snail disposal is your goal. But they'll keep coming and coming... unless you address the root cause of your snail problem. Then you won't have an overpopulation of them, just a healthy balance. The source of a snail overpopulation is overfeeding the inhabitants of the tank and/or inadequate tank maintenance. (I'm not trying to judge, I'm just being factual.)
How often do you do a partial water change? How much water do you change? Do you use a gravel vac? Which and how many live plants do you have? (I think I see Anacharis and possibly a sword.) How long as your tank been set up? What are your readings for Ammonia, Nitrite, and Nitrate?
I can see from the amount of gunk in the bottom of your breeder (as pointed out by Tazman) that, especially in a tank that small and heavily stocked, your water quality is very likely to be poor and your fish suffering. I would add that it is likely that your Guppy lost her babies due to poor conditions. I also suspect this is why you've had so many losses (from your "passed away" section in your sig). Making this situation worse is that your fish are breeding and adding even more to the bioload with each baby. (You'll want to acquire an additional tank for growing out babies in the future, or removing some fish from your 10g to make more room.) We need to sort this out so you can have healthy fish who have healthy babies!
