How to know if a field of water can be fished?

Question

Some people like fishing in Tibia as a way to get some free food, since a fishing rod and 100 worms are very light to walk around. However, how can I know if a certain river or lake contains some fish on it before I start using my rod on it? I have this problem specially with underground bodies of water.

Answer 1

- If there is no fish in the water you will receive the message Sorry, not possible. This only applies to water that is always unfishable. Does not work on a square where a fish has been caught.

- An easy way to tell when you have caught a fish is to watch the amount of worms you have.

- You cannot catch fish while fishing from a Protection Zone.

- Your fishing skill will only rise if there is a fish in the square you are fishing in. This is a good way to check is a fish in the square.

Answer 2

Mostly all of them contains fish, only some shallow water that doesn’t contain fish but I think that the best way of knowing if a water has fish on it is using your fishing rod... if you don’t receive the message “you cannot use that object” then you can fish in that place.

Answer 3

It seems that with all water bodies except the fountain you can get fishes :)
