How often do I feed cories?

Well I have two relatively small cories about 1" each. I had 3 of them but one came from the store really skinny and died the next day. Well I have been taking about 2 pinches of Tetra tropical fish flakes and crumbling it up and shooting it to the bottom with and eye dropper. I do that once in the morning and once at night. This is also for my two neons to feed on. My question is, is that enough or is it too much, there seems to be a little bit of waste left afterwards but I dont want them to starve, it also seems like a big amount of food going into the tank so I do like 20% changes 2x a week. I figure it would be easier to just ask you guys.

I feed twice a day for adult fish but three times a day or more for young, growing fish. The amount to feed is really hard to just tell you straight away. Usually the recommended amount is "as much as your fish can eat in a few minutes" but I don't really think this gives an accurate picture. Cories are scavengers. They can usually smell when food hits the water, but they tend to cruise around the bottom feeling for food. There's no way they can get a good serving of food in just a couple of minutes. For this reason, in tanks with cories I try to have enough food land on the bottom that it takes the cories roughly 20-30 minutes to find and eat all of it. Granted this takes into account the population density as well as the amount of decor I have in my tank. Really, you just need to watch them eat and you'll start to get a good feel for how much you need to feed them.

For young growing cories like yours, supplementing their diets with frozen and live foods can really entice their appetites and encourage growth. Things like bloodworms, tubifex worms, brine shrimp and live blackworms will be gobbled up like nobody's business.

Corys do extremely well on tablet food that sinks to the bottom immediately. They will gather around a tablet in a group and eat for several hours. Flake foods do not do it, even when directed to the bottom. I have a shoal of several cory species in both tanks and drop in 2-3 tablets (three types, alternating each day) when I feed the flake in the morning. If you stick to approximately the same feeding schedule (I do mine about an hour after the tank lights come on) they get very used to it and will appear in anticipation. In the early evening I feed frozen bloodworms which they really like as mentioned in the preveious post.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

I agree about the tablet food. Get a sinking pellet or wafer specifically for bottom feeders. My cories love Omega One sinking shrimp pellets. I also use Hikari sinking topical wafers. I alternate these throughout the week along with frozen bloodworms or brine shrimp. I feed my cories once a day.

The Hikari wafers are a fairly small diameter so for your 2 cories 1 wafer would be plenty. The shrimp pellets are small also so 2 of those would be fine. Your other fish will like them also. You may want to think about getting a couple more cories. They really prefer being in a group.

I have 6 green cories and 6 danios and when I feed the danios the cories scurry about but it does not look like any food hits the bottom as the danios are very agressive eaters so I drop 1 or 2 shrimp pellets in for the cories and always find the danios usually try to eat those as well. They all gather around and take turns pecking at the pellets. I feed them when I get home from work and they know it.

a simple way to get food down to your cories so the other fish doesnt eat it is with a piece of pvc pipe...........Simply put the pipe in the tank with an open end up, where the cories will see and smell the food.......just drop your sinking pellets or wafers inside the pipe, they fall to the bottom and out the other end of the pipe, hopefully right in front of your cories............If the other fish dont see the food falling, there is less of a chance of them eating it
