My pearl gourami are gasping for air for a very long time and then they go back to exploring the tank so I am worried something is wrong.. I added 6 rasboras hengeli yesterday and 6 bronze cory (I will get more) and they all act fine. My tank is a month and a week old or something like that so I don't think it has something due to ammonia or nitrite. I did a small water change just in case but should I add something like an ammonia sponge that I have or seachem prime just to be sure?
