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.

Were you considering putting crushed oyster shells at the bottom as substrate? It is best to place the oyster shells in the filtration system.

Actually I mixed the two together and it looks rather well. The tank has an Eclipse III hood so there isn't an easy way to put it in the filtration. I am letting the tank cycle with some water from an established tank and we'll see what I can come up with. I have since been told that a pair of GSP's will quickly become too large for a 29g tank and I would be better off with figure 8's. Any advice?

Is that right? Spotted puffers get that big? The fish store person told me my spotted puffer would get a little bigger, but I didn't think it would get that big.?.? How big are we talking about? Right mow my puffer couldn't be more than 1.5" long.
