    Hi I have a 5 gallon tank with 1 glofish, (others died, getting more this weekend) and I have a thin layer of like a film at the top of my water. Is this normal?

    welcome to the forum

    Yes, it's normal (in that it's not uncommon), but no you don't want it. It is likely a protein film or something, and can interfere with the O2/CO2 exchange. Are you feeding flakes? They are the usual culprit - low quality food makes a mess.

    Also, it normally happens when there isn't enough surface agitation, so that's another thing to look at.

    I agree, its usually the result of either cheaper food, lack of surface movement, or both. Adding an air pump with stone will usually solve the problem quickly and easily.

    Thanks, I did a water change to stir up the water and it helped :;banaman
