Kribs Rip ?

[Royston]

Lost my pair of kribs and don't know why....... All water parameters are fine and all the other fish are good.
Both kribs just lay near the bottom and were gasping, couldn't see anything out of the unusual on them. Is there a certain desease just kribs get ?

What size is your tank? Do you have an airstone?

How old were they?
We're they acting funny before death?

Also, you say the water was fine but what are your water stats?

Temperature, lighting times, etc might also help.
