    Tank upgrade or stay?

    Hey all So I have a 40B. I have an opportunity to upgrade to 75 or 125. Problem is I don’t know which. I have one filters rated for 100, plus skimmer and Uv rated for 100 and 200.

    Starting 40 breeder with one AI Prime 16HD?

    I am planning an upgrade from my evo 13.5 to a 40 breeder, and am looking for a light setup that will work well for my tank without breaking the bank. I like what I have read about AI Prime 16HD’s, but I can’t afford 2 of them at the moment on top of the cost of the new, bigger, tank setup...

    Longnose hawkfish yawning?

    I’ve noticed since I got my longnose hawkfish about 4 month ago that he tends to open his mouth like he’s yawning. I tried to get a picture of it for like an hour but of course now he won’t do it. Is this just a thing they do or should I be concerned.
