I have two patents for this hobby, one was a seahorse feeder that I used to sell 25 years ago.
I sold thousands of them and they were sold mainly by a marine wholesaler that we all know.
I have long since stopped making and selling those and the patent ran out.
My other invention sells well and I gave away the business. I still own the patent so I get royalties.
I also wrote a book shown under my posts. It sells pretty good but I do not get a nickel from it as all proceeds are donated to Multiple Sclerosis research in my wife's name.
As for my tank itself, I never sold anything from it as I prefer to give anything away rather than selling it.
