I'm almost positive it was some type of internal parasite that killed all 3 or thy just shipped horribly and I got the best of the 3 that was still dying. It wasn't pyramedial snails I checked it over also My water quality is fine I keep acros alive, colorful and thriving. IMO
all clams require about the same water quality it's just Maximas and crocea require more intense light. I was more trying to save it then anything so I guess I learned my lesson lol. Ill definitely be trying another deresa in the near future.
