I finally add some fish after about a 6 week cycle. However, after about 2 weeks, I have begin to notice an oily film on the surface of my water. I've been researching and believe it is because of overfeeding or they type of food. I've been feeding once a day, every other day and only a small amount (at least to me it is a small amount). Thus I think it is the type of food. Could one of these foods be the culprit that's contributing to the oil slick.
Tetra BloodWorms (Freeze Dried)
Omega One Shrimp Pellets
Tetra TetraMinPlus (Tropical Flakes)
I have a Fluval 406 with the outlet in the left back corner just below the surface pointed toward the middle of the tank. I'm thinking about adding a koralia nano 240 on the opposite side to move water across the top from right to left.
