Thumbs up Go for it!

I see no reaon why you should not be able to keep corycats and goldfish together. They are both very hardy fish, particularly goldfish. I have four corycats in with a mystery snail and a betta, with no heater and/or filter, and they are healthy and happy with frequent water changes. I also have golfish in a small outdoor pond, and they live in freezing temperatures as well as boiling hot summer temeratures... they have been there for years, and everyone is dead. I would definately go for it, but I suppose it is just a matter of opinion. Good Luck!

As for the hardness, I didn't spot this although with a lot of work one could probably deduce it a bit from all the various minerals. I was looking particularly for calcium and magnesium and didn't see either mentioned. Ask your local fish store, they have probably tested the water themselves. They should at least know the answer, hardness and pH can be crucial to some fish.

I agree with Byron on this, however. Fish, no matter what kind, should be living in chlorine-free water. Unfortunately, the better part of tap water these days does have chlorine, so you should probably add some water conditioner to your tank water. You can find this for a couple of dollars at any pet store or online.

I just wanted to add that even if you are keeping your goldfish at a higher temperature which the cories can tolerate, there HAVE been reports floating around the GAB of goldies 'choking' on cories when they attempt to swallow them and the cories stick their barbs out. So I wouldn't risk it.

A more suitable bottom dweller IMO would be the tested-and-true goldfish janitor, the bristlenose pleco (given you are heating your tank to at least 74).

no wonder we don't get that problem here due to our wonder we can keep those 2 together here

Temperature is not the issue. I'm echoing Kelly's call on this one. You are forgetting that a lot of goldfish variants can gain a size of 8-10" with singletails at 12-18", very easy enough for them to fit small cories in their mouths once they attempt to gobble them. You will find that in goldfish forums, we do not advise cories as one of the compatible tank mates. There have been a few cases of goldfish ending up choked to death after swallowing a corydoras that lodged its spines in the goldfish's jaws. In this case, either or both fish will die.

If you insist on bottom dwelling tankmates however, then bristlenose plecos or dojo loaches certainly are choices to consider. Just make sure you have adequate space and filtration as the plecos do poop a lot rivaling that of goldfish. Ideal temperature for goldfish in general is 72-78 degrees Fahrenheit. A compromise can be made between two species with opposite temperature requirements as long as they are compatible with many other similar requirements, most especially diet. In some cases, that is not possible. There are many things to consider why some species just do not mix.
