I have a little cave that my betta Dr. Augustus Pablo has clearly made his "lights off" residence in my tank. I would like to custom paint it upon my next cleaning of the tank (coming up very soon).
Can anyone tell me which type of paint to use, give me any pointers, or tell me that this is just a horrible idea and I should drop it?
Keeping the health of the fish and the tanks biosphere healthy is first and foremost but I also want Augustus to roll with style when possible. Thanks in advance.
