Thank you VERY much.
I found a used 30g on craigslist. I got it free. It is severely scratched and would never make a good DT anyway. Perfect QT tank. I just need to clean it out. I plan to use a baking soda slurry and warm water. I'll scrub it with a new sponge and rinse heavily.
Should be ready to QT these fish by the end of the day.
