Betta Fish: Sorry for the bad photo angle but I saw this awesome sign and thought you guys would appreciate it.
Aquariums: Independent pet shop told me two days ago to do a 50% water change as ammonia and PH were high. They were happy to sell me fish (I didn’t, as I don’t want unhappy fish and read ammonia is a no). Did the change 2 days ago, and tested at home today. What’s next?
