Copper Sulfate In Api Algae Eater Wafer Safe For Shrimp?

HI guys!

I recently purchased some of the API algae eaters in the hopes that I could feed them to my shrimp. However, I just looked at the ingredients list and found copper sulfate in it. I know that RCS are sensitive to copper, so would this be harmful to them?

Don't have shrimp yet but I will be getting some in 1.5 months so that my tank can establish itself a bit more (started the tank on April 25th currently is cycled with 0 ammonia, 0.25 nitrite, 10 nitrate).

I would like to know if I threw my money down the drain or not.

This is what I bought: API® Algae Eater Premium Algae Wafers Fish Food | fish Food

There shouldn't be enough copper in those to hurt them.

You would think any amount of copper would kill your Cherry Shrimp, but they actually need a very minute amount to live. You will be good with using that as food.

Yea the problem is they don't list the amount so I was worried that it would kill them

How did you kill them?

I've seen a lot of people on here who feed them, so I think you should be ok. Personally, I usually order the ones without the copper, but I can't say I've ever seen anyone with bad experiences from the ones that do have copper. Congrats on the upcoming tank! Shrimp are definitely one of my favorites

I have used the same ones containing the copper and my Amano Shrimp go nuts for them. I also have used them with my RCS (cherry shrimp) and have not had a problem, though I would put two in once a week. I stopped as I figured they get enough biofilm and algae naturally and they are not really needed.
Cory’s like them as well.

Bottom line I think they are fine, you will notice some ferts also contain small amounts of copper they are fine to us as directed also, if you go planted tank that’s to say.
Enjoy your shrimp, I am happy you not rushing the tank let it get cycled and stable then add the shrimp.
Just out of curiosity where are you going to get your shrimp from? And how many? Any other inhabitants going in the tank or is it just for them?

I currently have a betta in there (I've been considering switiching it out for 6 neon tetras). I was either going to get them from a big Al that's near by or get then from someone on kijijI or FB group. I was thinking of starting off with 10. I live in Toronto Canada (idk if that shows) if you have any other options I'd be glad to hear about them.

Betta and neons may eat your shrimp. They will most definitely eat any zoes (baby shrimp) you may end up with.
IMO don’t mix fish and shrimp at the start get your Colony going and then maybe add some small non-aggressive fish

cool I really can't get a clear picture in my head of what I want. I read last night that Tetras need two feet to be happy so I might just go with chilI rasboras

Cherry barbs would do better in a 2 ft tank as well, but embers or chilI rasboras would be great in a 10!

Great! Now I just need to make up my mind

Chilis would be better with shrimp, I think - I don't even think they could eat most of the babies because they're so tiny.

Red Dwarf Rasbora (Microrasbora rubescens)- up to 12 --> from Anders247 list

I think I'll go with 8-10 so I can keep the shrimp too

10 would be great! They're so tiny, I think you'd be fine with 12-15. On Anders' 10 gal stocking list that's stickied in the stocking subforum, it lists a max of 12 for all of the Boraras species, but having kept both B. maculatus and B. brigittae, I think up 15 to B. brigittae would be fine - they're smaller and more slight than B. maculatus, so I think more would be fine.

So you could do 12-15 and 10-20 shrimp (to start - they'll breed and soon you'll have lots)? I don't think having more chilis means that you can't have more shrimp too.

They should be less stressed in a bigger group, yes
