Vincent has taken a turn for the worst, and this time he's not going to get better. His organs are failing =/. Right now I have him in a bowl that's probably about 1/4 of a gallon, and its not even halfway full because he can't reach the surface for air. He won't be able to return to his 2.5 gallon, so I'm wanting to sterilize it for the next betta that will call it home. I'd like to use the vinegar solution to clean it since I'm a little wary of using bleach... but its going to be a very hot/sunny week so i'll be able to let it sit and bake in the sun for several hours after i wash it.
So basically, i just need to know:
How much vinegar should I use to clean the tank??
And can you clean sea shells with vinegar, or am i just going to have to throw them away???
(btw Vincent doesn't have any terrible contagious diseases that i know of, he's dying of a tumor)
