Evening everyone, I know this isn’t a saltwater post, but I was hoping someone here could help. I have a pufferfish currently in brackish water. It will eventually need to be acclimated to saltwater, but I added it to a fully cycled tank, about a week after I added it, i noticed the fish at the top, breathing fast...so I tested the ammonia and found it .25. It spiked to 1, nitrite spike to .25 for a few days before dropping. The ammonia is still high, the fish still isn’t eating, and getting thin. I asked people on a Facebook pufferfish page, as well as our local group, I was told to use seachem prime and seachem stability along with continuing daily 50% water changes. But the ammonia just isn’t dropping. The feeder shrimp I put in are doing fine, they don’t seem bothered by the ammonia. The puffer is in a 55 gallon with a specific gravity of 1.10.
