Is it possible to keep wild caught saltwater fish as pets?

How to keep salt water as a pet?

I have a green spotted puffer. I was wondering if it could be happy with an algae eating fish in brackish water?

Two of our freshwater fish are acting oddly in the water. We did lose a few last night, due to an ammonia spike. We noticed some pale-colored, wormlike flesh dropping from the front area (between the mouth and front fins); this black Guppy is “wobbling” around... We also have an orange Molly fish that has been staying on the bottom, not eating or moving much. Attached are pics, for your review. Can you please provide advice for these issues, we want to try our best to save them!
