Copper Sulfate And Inverts

[dizzied]

Probably a dumb question.

Does the copper sulfate found in some fish food harmful to inverts?

Probably a dumb question.

Does the copper sulfate found in some fish food harmful to inverts?

Depending on the amount, I would avoid feeding any that have it to tanks containing inverts.

A lot of my fish food contains copper sulfate it seems. I wonder if this could've been the cause of my massive snail die-off a month back.

I'd like to know if anyone has any facts on this.

I remember reading somewhere in pfk that someone decided to feed cichlid pellets to their shrimp, and the shrimp all died. On later inspection, it appeared the pellets contained copper (presumably copper sulfate).

Strange. I've been using this brand of pellets (containing copper sulfate) for 6+ months. It was my snails that died off, while the shrimp were unaffected. Perhaps snails have a lesser tolerance of copper?

 

[three-fingers]

Possibly, but shrimp in general are less tolerant otherwsie, I suspect that my first amano shrimp were killed by the copper in the water from my hot tap (which I now no longer use) while the snails were OK.
Could have easily been another unknown reason for my shrimps death though.

Since your shrimp are OK, this would lead me to believe that it was something other than the copper that killed your snails.
Did the snails just die off recently?
And were they all the same species of snail?

I did post the snail problem some in it's own thread some time ago. But they did die off about one month ago, mysteries and mts. I originally tried to find out if there was a chemical that was shrimp-safe and snail-unfriendly, but didn't get any answers.

Was it from all the NH4 waste from the food or was it the Copper?
You cannot say based on those results.

NH4 is pretty toxic and there's a lot more in fish food than the require toxic amounts of Copper.
Also, where is the control here?
There is none, they are just guessing that the food killed their shrimp.

We need copper as do shrimp, the issue is how much; too little, you have a deficiency, too much, it's toxic.

Shrimp die for many reasons, that have little to do with food, or plants or or.........folks kill them all the time without having done or fed these things to them.

I use shrimp for toxicity models, they are cheap and easy to test with.

Thanks for the answer one year later?

Anyhow, it was concluded that it was indeed copper that killed off the snails, as I've found others who've been having this problem in other forums.
