Lately we've been noticing that there are bubbles/foam looking stuff on top of the water in our Axolotl tank. Blacky (our axi) is eating normally, we havent changed or added anything to the tank and the water quality is all normal.
Does anyone know what might be causing these bubbles/foam substance on the top of the water?
