Ok, I know they are brackish fish but when I get them I'm sure they will have been kept in freshwater and I will be acclimating them. My question is about substrates. I know they need a pH buffering substrate like crushed coral but would a mix of gravel and oyster shell be ok? I like the look of darker sub. but want the buffering capability also. Thanks for any help.
