I'm not sure about the crazy glue.I would think once it has set,water won't dissolve it,so it would probably be safe.But please don't take my word on it.
Have you tried silicone?

[iZinedane]

i dont know about that
your best choice would be aquarium silicone

I would use silcone! Its proven aquarium safe!Just leave it set for a couple of days!
There is a glue that a few members use but I do not know the name of it.

NO NO NO any kind of super glue is not safe for fish. The chemical hardeners used to make it dry so fast and hard release toxins. That's why everything around them turns white.
Stick with 100% pure silicone like GE I or II or the tank sealant you get at the petstore. It's proven, no guessing, safe and cheap. Best bet.

In reef tanks we use super glue gel to glue frags down....... advice from RC

I am going to flatly say that is wrong. I have used super glue several times in my tanks with absolutely no ill effects. I have attached java moss and fern to driftwood and the plants and fish thrived. Reef owners use superglue to attach frags all the time. It has been proven multiple times to be safe for use in the aquarium.

From wikipedia: "The fumes from CA are a vaporized form of the cyanoacrylate monomer that irritate sensitive membranes in the eyes, nose and throat. They are immediately polymerized by the moisture in the membranes and become inert."

Water will instantly render any super glue instantly inert. The only hardener used for most super glue is... water. Thats why your skin bonds instantly, the water on your skin instantly sets it. Underwater, super glue sets even faster. That white dust you see from hardening super glue will never happen in water since the water instantly hardens the super glue. The only damage a fish would suffer from super glue is if you used it to super glue them to something.

I think you're both a little right and a little wrong on this one. If we are talking about the brand name 'Super Glue' it will probably be fine in the water although I've heard accounts that say otherwise.

If you're using some generic brand of super glue then just be careful. Some of the cheaper generic brands contain other residual chemicals due to manufacturing that do not become inert in water. For example I know at least 2 brands that can be bought around here contain low does arsenic salts. My ex-roomate did a full mass spectrometry analysis of various adhesives as part of his thesis on surface topology. Overall it's far below the level toxic to humans (unless you ate a ton of the stuff), but I certainly wouldn't want it in my tank water.

I think either way I would just stick with aquarium silicon. Or even better, try some live plants

What kind of plants were you using that were falling apart? Can you post photos?
