Golden tench in OSRS is mainly a collection/log flex item from aerial fishing, and if you get extras, the usual use is to keep one and convert or drop the rest depending on what you’re doing with the activity. A recent discussion notes players can get multiple while chasing a fish sack, so it’s not treated as a unique one-and-done item.

What it’s for

  • It’s associated with aerial fishing on Molch and is commonly chased alongside the fish sack.
  • One player discussion describes it as useful mostly because of its terrible combat stats in certain niche setups, not because it’s a strong normal weapon.
  • For most players, it’s a novelty/collection item rather than a practical training weapon.

What to do with it

  • Keep it if you care about collection log progress or rare drops.
  • Use it only if you specifically want its niche behavior in a very particular setup.
  • Drop or bank extras if you’re simply grinding aerial fishing and don’t need duplicates.

Practical advice

If you got one and are wondering whether it has a big money-making or combat purpose, the answer is basically no. The most common advice from community discussions is to treat it as a rare side reward from aerial fishing rather than something you build a strategy around.

TL;DR

Golden tench is mostly a rare aerial-fishing collectible, with a couple of niche uses, but for most players the best move is just to keep one and ignore extras.
