I had the shovel nose for 3 yrs. I got it at 3inch. It was in a 1600gal pond with a giant gourami. He was 25inch when he died. Ok now ill tell you what happened. I had just reached home and i see the shovelnose not being able to swim properly. So i went close just to see his belly full off air or something i dont know as it was soft. Thats when i msged on this group. The water parameter all ok. No issue with the water. Another thing is i live in india and getting your hands on fish medication or anything for the matter is like searching for diamonds in your backyard. Its very rare that you will get any proper fish medication. The fish died very fast but i did everything that i could
