Animals we can't sell

Moss & Molt follows federal and state rules on shipping and owning animals. Please don't apply for anything in groups 1 and 2 or the last two lists: we can't list it. Group 3 can be listed, but it can't ship to some states. Animals are A to Z in each group.

Also never accepted

Federal law (Lacey Act, Endangered Species Act, CITES).

  • Animals collected, bought or shipped against any state's or country's law

We don't list (our choice)

Not against the law. We don't list these to protect the animals and our customers' tanks.

  • Dyed, painted, tattooed or color-injected fish (e.g. painted glassfish, colored botia, dyed parrotfish)The process harms the fish and the color fades.
  • Fish that grow over 2 feet (e.g. iridescent sharks, tiger shovelnose, clown knifefish)Too big for home aquariums.
  • GloFish and lookalikes (fluorescent genetically modified fish and fish made to look like them)Licensed brand fish; we leave them out.
