My turtle Drake, is about a month old now. Currently using the Exo Terra Solar Glo MVB bulb 100 watts, a 30 gallon tank that is a little less then half filled, he also has a basking area, which is made out of drift wood.
Recently,a white lump has appeared on his neck, its not cottony and stuff, in fact, it seems like a zit or something, should i be concerned about this ? The lump is pale grey, i went to a pet store and bought some tropical fish fungus treatment, will this work?
