Yeah magpie shipped me 3 that she had for quiet a while. She used wetspot to ship they were totally fine. Poly species ship well I think from their ability to breath air. As long as there is enough air in the bag they should actually ship better then most fish.Why did you put captive in quotation marks?
I get that they tend to be weakened from capturing and die often in quarantine but do they ship well? I’m thinking that if they ship well I might buy them from other aquarists instead of playing Russian roulette with my lfs.
