Twistermom, I'm not an expert much less an ichthyologist.lol I just try to help wherever I can.
It's going to be difficult to take "side" views. These are pond fish and I do not have an aquarium. Bumps appear to be soft, but I haven't tried to catch a fish to push on one. Occasionally, a bump collapses and the fish is left with a large white lesion. I will purchase a tester kit and let you know what the readings are. The pond is about 4 years old. Located in Phoenix, AZ and subject to our high temps during summer. I struggle with algae bloom in summer and use algaecide and blue dye to cut down on UV. Maximum depth is 4' with some more shallow areas. Plenty of shade available via deck overhang and water lily leaves. I saw pictures of identical gold fish "bumps" on another web site but no one had responded as to cause.
Here is a link to another website with fish with identical problem: http://www.goldfishconnection.com/ar...76&parentId=12
