Is iron (Fe) safe for dojos, kuhlis, and shrimp?

Also, which ferts could be potentially harmful to certain fish?

Yes, iron (Fe) is safe for dojos, kuhlis, and shrimp.

I know of no ferts used for planted tanks that are harmful to any fish.

Shrimps??? Don't know. I once had 25+ Amano Shrimps. Well, they were all dead maybe 6 months ago. Could be from EI dosing or high CO2 level. Back then I wasn't even dosing iron additionally.

Amanos are fine with EI dosing and high CO2 levels. I have over 50 in my 90g tank and just added 50 in my 75g tank. Both tanks are dosed EI ferts and have very high CO2 saturation (yellow drop checkers). In fact, I have found that amanos can take a higher level of CO2 than fish.

According to wet's fert calculator if you over dose Plantex CSM+B you can have too much copper for "some sensitive fish and inverts"... You have to really screw up to add that much though.

I don't know where he gets his % from copper toxicity though, so I can only repeat what it tells me. And I guess you could say the same thing about anything you over dose, but I never would of imagined you could overdose plantex.

Should I try again the second time? Maybe my temp was too high? What's your tank temp?

My temps are high. My tanks generally run around 80-82°F.

Amanos are really hardy shrimp. Is it possible the tank had ammonia or nitrites?

I doubt it. Fishes were fine. The tank was setup around early August. I didn't add shrimps until Winter. I suspected some sorts of bacterias maybe. At first I thought maybe my Chinese algae eater was killing them..until I saw one of the shrimps just dropped dead while clinging onto a leaf near the water surface...before the CO2 was turned on. I once rescued a shrimp (which has just dropped dead literally seeing it right before my eyes) from my tank by putting it in my pre-treated water. The water was cold. No ferts or whatsoever. It came back to life. I kept the tank temp around 80 degree too.

At that warm temperature is there plenty of water circulation? Warmer water holds less oxygen. That the shrimp revived in cooler water suggests something like that.

It could be. This was what I saw. At one moment, the shrimp was feeding off some leaves. Then, it stopped moving and slowly sinking to the bottom of the substrate.

That could explain things. While my tanks run hot, they are very well oxygenated with good circulation, even with the CO2 saturation so high.
