there are 2 ghost shrimp varieties. amazonian and american. neither of them are agressive at all to fish mabey to other shrimps but not to fish.
the problem with "ghost shrimps" is that any clear shrimp will be labled "ghost"
the agressive ones are really Red Claw Macro most likely females.
the "real" ghost shrimps are Palaemonetes paludosus and Palaemonetes ivonicus
these are the ones from america and amazon respectivly.
kinda sad that an outa work carpenter who is a highschool drop out is having to explain this to yall.
by the way this is my last post on the subject and the only reason i commented is cuz i saw the reference to "dragon eel" which is normally in a fresh water context a Gobioides broussonnetii
, Gobioides peruanus or Odontamblyopus rubicundus
common name violet or dragon goby. also sold as dragon fish and dragon eel.
misinformmation on this fish is annoying to me since it is not aggressive not fresh water not a dragon. they grow to be 15 - 20 inches are brackish and need to be made sure you feed them proper. given that they live in s.g. 1.005 + brackish water they are totally incompatable with bettas. they need 40 gallons to live in.
when kept in fresh water die from bloody red tumors some even on the mouth so they starve to death. in fresh water if the tumors don't get them renal and liver failure do.
the possible exception is the betta mahachai who is found in SEMI brackish water but even then the sg is still to low for a violet goby.
