Alright so I got him and he's so tiny. He's about the size of my thumb nail and I was wondering is I should add him to my 55g brackish or if I should add him to my 25g freshwater until he's a little bigger. The 25 does have a really fine sand he should be able to burrow into. The sand is actually from the beach where I found a wild flounder burrowed. View attachment 284617
Keep calm and drum on
There's a 2 part answer to that question. Part 1: If the store you got it from had it in straight freshwater then I would put it in your FW tank for now but will need to convert it to brackish in time. Part 2: If the fish in your freshwater tank won't allow the flounder to eat, then you need to set up something for him to be able to do that. These fish are not scavengers. They are opportunistic feeders. So if no food gets down to them, they starve.
