Aren't methylene blue and pH test indicator solution the same thing?

Wondering because I transferred some cory eggs to a small tank to try to hatch and read that adding methylene blue is recommended to prevent fungus. I thought "I don't have any methylene blue." But then I remembered that, I think, pH test indicator is methylene blue.

No. From doing a bit of research it appears that one of the chemicals in the PH test solution is bromothymol blue.

Oh, right. Got my "blues" mixed up. Thanks. Probably won't make it to the pet store to get some methylene blue until the weekend. By then the cory eggs will probably either hatch or die. I've had cories lay eggs all over the tank several times, but to my knowledge none ever hatched. This time I just happened to have just set up a small plant-only 5-gallon tank, so I thought I'd give moving a few eggs a shot.

If you can find alder cones they work just as good (if not better) than methylene blue and will not stain your silicone blue.

Well those little cones look sort of familiar and I think maybe I've seen them somewhere sometime in my life, but I don't think it's something I could just go out the woods and find. If it's something I'd have to buy online and get shipped here, it wouldn't be worth the bother or expense for a few eggs that I think are probably not viable anyway. It'd be cool if some of the eggs hatched, but if I want more cories it would be less trouble to just go buy more adults.

That's true. It is less trouble to go and buy adults. But it is fun to raise baby fish. If it's something that you were interested in trying alder cones are widely available from a number of online retailers.

OMG! OMG! I just saw a really, really teeny, tiny baby cory scuttling around the 5-gallon tank where I transferred some of the cory eggs to! OMG! Gotta find something to feed it!
