Blind Cave Tetra/fish

[Jake Jackson]

Would I be able to acclimate blind cave fish to brackish conditions?

 

[The-Wolf]

both Astyanax jordani and the more common Astyanax mexicanus
are true freshwater fish and should not be in brackish water at all

if you are lucky and manage to find any Milyeringa veritas Cave gudgeon
they are found in both freshwater and brackish water caves
as is Ophisternon candidum Blind cave eel
