Read it again, folks. He's treating the ich in another aquarium. The main one is 65 and sans sponge filter as he moved it to the hospital tank with the fish. And yes, an air stone would probably be greatly appreciated by the shrimp.
I took out my tetras and put them in a 5g (not sure of amount of water it's one of those large acrylic pet carriers). And took out my sponge filter and heater from my main tank (20g) to put in with the tetras. I raised their temp to 82 degrees and added about a tablespoon and a half of kosher sea salt.
Right now my shrimps are in the main 20g tank and I plan on doing 50% water changes everyday to clear out the substrate of any lingering ich. I've just started with a planted tank but I have quite a few plants in there now with the shrimp. Don't have an extra heater to raise the temperature for the shrimp. I'll throw in an airstone tonight.
Couple of more questions:
1) What does ich look like in a tank not on a fish?
2) when I first got my shrimp they were colorless and then in a day or so they turned a rich red. But now that I changed the water and took out the pump and heater they lost a lot of red....are they dying?
3) Will and can a baby shrimp escape the suction of a gravel vac?
