My ph seems to be about a steady 8. I have two balloon mollies, and i just got a small, what was called "catfish", but it is not like the larger pictus ones or anything. its small, im told it stays small, its albino, and you can kinda notice a greenish irredesent shiney spots on both of his size. he has red eyes and his mouth comes to a little point kinda, with little tiny feeler thingies. Im kinda concerned about my ph, since i just did a water change with a little over 2 gallons of distilled water (i have a 10 gallon tank). Ive heard the mollies are fine with the higher ph, but im not sure about the other fish. Since i put him in earlier, he swam around a bit, but he mostly is hanging out in the back corners. I also noticed my male mollie kinda nipping at him, but it didnt seem as if it was doing any damage, and the catfish never fled....
