ich in shrimp

Recommended Posts

as i believe shrimp cannot get whitespot/ich disease is it possible for them to be carriers, and if so how long can the spores lay dormant on the shell

May be species specific, which means that they can't get ich at all, let alone be carriers.

 

Could be wrong.

Mostly using the wiki as the source: https://en.wikipedia.org/wiki/Ichthyophthirius_multifiliis

Two main bits in this stick out to me:

Quote

This life cycle is highly dependent on water temperature, and the entire life cycle takes from approximately 7 days at 25 °C (77 °F) to 8 weeks at 6 °C (43 °F).

Quote

New tropical fish should be quarantined for at least four weeks and cold-water fish for eight weeks. Also, washing your hands before and after maintenance of each tank and using separate equipment will reduce the chances of spreading the parasite between tanks


So it will depend on the temperature you're running at, but ~6 weeks sounds like it should be enough, so long as there are no other hosts (Fish) in the aquarium for them to feed on to preserve their cycle.

 

As a note to how they spread/reproduce:

Quote

After it feeds within the skin or gills, the trophont falls off and enters an encapsulated dividing stage (tomont). The tomont adheres to plants, nets, gravel or other ornamental objects in the aquarium.[1]

      The tanks are only 16L, for it to reach 31c, it isn't hard.

      Sorry to hear that.  Wow, the temperature must have been very hot for the water to get to 31degC.

      It's room temperature, during the past week Hong Kong has become an oven. I will get another water cooler before I start again. The 3 shrimps seems to be doing well for the past 11 hrs.

      Well, what can I say, de ja vu, was it a heater malfunction or just ambient room temperature? I wouldn't hold out too much hope for the 3 survivors either if my experience was anything to go by - but I will keep my fingers crossed they survive! Really sorry to hear the news and if anyone can feel your pain that would be me. Hopefully you can just remove the cooked shrimps and start again without having to go through the whole process of re-setting up the tank and cycling from scratch like I am? Hope everything is going well with the old tank. The shops sound similar to ours in old towns, they started as houses and then get divided to shops street level and basement and the upper floors are either offices or residential. Simon
