Well, obviously, if there is a rotten smell to it, just like any other meat, you wouldn't want to eat it. If the color has changed, greyed, you shouldn't eat it.
If you are wanting to know how to SHOP for fresh fish and avoid the older stuff that's on its way to going bad, the first indicator is smell. The more it smells like fish, the longer its been out of the water. You're looking for more of a sea water smell, and not fish smell. Look for firm, somewhat clear looking flesh, if its mushy or off color, you might want to select something else.
cuz it smells of fish :)
Only a fish would know the answer to that and unfortunately they are unable to tell us.
I would see it/them.
yes
Did you know that there are so many different kind of fish and not all of them have been discovered.
There hasn't been any information on what is the shortest fish, all I know is that the skinniest fish is the Trumpet Fish. But I have no idea what is the shortest fish.
I would say they may have been good fish to start. But I know the Walmart by me neglects their fish and I would never buy one from them. When you are selecting a betta be sure to look for good color, clear eyes, smooth bodies and no protrusions.
I don't know if you would call it a dinosaur or not, but I think they've found a fish fossil.
fish have been know to be both preditor and prey. it all depends on the species and size of the fish.
The Shark's and Whale's are fish so I would probably say them otherwise I don't know!
I do not know. I would highly consider asking you local fish veterinarian.
how would any one know that?????
