Hy I just got two mickey mouse fish the other day along with two large zebra danios they are an inch long. Well both of mickey mouse fish just kinda chill at the bottom of the tank and they eat what ever food sinks down there and one of them has a light blonde patch of scales on his side I was wondering if it is because he is stressed or what. I go fish for cycling my tank I was originally going to go fishless cycling but I coudn't find plain ammonia.
