Teacup Stingray died.

Sorry to hear that your Stingray died.

Yeah. I strongly suspect it was the liquid carbon ( used for the plants) also. Just trying to get some good confirmation. Looking for the thoughts from some experts. Should I start a post about liquid carbon and see if anyone has had negative experiences with it?

I don't know anything about rays but im a little curious why you would use liquid carbon and excel? Generally if your going to dose excel thats about all your going to get out of dosing, I see no need to add another product.

Very sorry for the loss!

As for flourish, I had that stuff wipe out a lot of fish in a community tank (I confirmed it the hard way when I refused to believe it.) I'll NEVER trust that stuff. For delicate fish, I would not think it is a good idea no matter - even if my events were not related. Why take a chance? If you need CO2, get a tank and bubble it in - that is very safe (within reason.)

So are you saying for sure that flourish has carbon in it already?

I have used excel on many sorts of planted tanks with fish such as bgk and wild caugjht angels. Never had a death from it. to answer op,yes,excel is a carbon source to give a sort of co2 to plants. In such a tiny,,and I do mean tiny dose as you did,Im certain that wasnt the killer. You could dump15 ml of bleach in a 140 gal tank and not harm anything if the perspective helps.Not that I would try it
for cermet. Co2 injection is hardly that safe unless it is very well set up and monitored,I cant think of a better way to nuke a tank then to have a huge ph drop and o2 depletion from a regulator failure and a large co2 dump into the tank.
for general knowledge,seachem flourish is a simple liquid fert,seachem excel is a liquid carbon co2 replacement.

Good to know the difference. I think ill give rays one more shot. Anyone know how much food a baby stingray should be fed in a day?

[smaug]

Your tank isnt big enough,give something more appropriate a try.And as I take a 2nd look at your tank,you can skip the liquid carbon as the plants you have are mostly slow growers without a need for much co2.

Smaug,
Thanks for the advice. I'm going to be upgrading to a larger tank probably late winter. I'm looking to grab a baby right now. The tank is 48" wide by 24" deep with the decor pushed to the sides, driftwood hung from the ceiling, and the center completely cleared out. Don't you think that's enough room for like 6 months. I can't imagine that if I get him at like 4 1/2 inches he'll outgrow it that quick.

healthy rays grow very quickly. they should be given many small meals throughout the day because they have extremely high metabolism rates and are always on the hunt for food and always producing ammonia.

btw, there is no such thing as a 'teacup stingray'. it's just a gimmicky name for baby rays used by petstores to sell fish. looks like your first ray up there was a hystrix.
