Hay Everybody, I recently post a thread about my cuz wanting another pay pup. Well he got one. He ordered it from a site that does Same Day Shipping or Next Day Air, don't know for sure. Well he said there is no problems until he nopticed the female swimming on the glass. He looked at her belly and saw a lot of red marks which he refers to "Ray Rash." He has the same sand as me which is Estes marine sand. His other ray he said looks compltely good on the bottom, no red marks. I was about to tell him "Why don't you do a 25-50% water change and add aquarium salt" Just want to check with you guys. Thanks
