That is the fishes droppings from the bottom.
There is no such thing as "fish loins" - well, not exactly. LOIN in reference to meats is defined as from the area between ribs and hips. This has no clear meaning with fish. Descriptions like "Tilapia Loins" is just a marketing thing, roughly like the description "Chicken Fingers." Or at best, fish "loins" just means filets from the side of the fish. But that's the same for all fish and not just a Tilapia thing.
Fish waste, or feces, varies in appearance depending on the species and diet of the fish. It is usually small and dark in color, sometimes resembling tiny pellets or strings. In aquariums, fish waste may accumulate as fine particles or settle at the bottom of the tank. Regular water changes and proper filtration are important in managing fish waste in aquariums.
Cats are very playful, and they see string as a toy. Biting and chewing are some of the ways a cat will play with an object. However, you shouldn't let your cat eat string, or even play with string, due to health risks associated with cats eating string. String can easily get caught around or block up part of the cat's digestive system which, in some cases, can be fatal. It is also quite possible for the cat itself to get stuck or tangled in string even without eating it. Surgery is usually the most effective way of removing not only string, but also rubber bands, thread, etc. This can be costly. Also, DO NOT pull on string coming out of a cat's mouth or butt. This can cut intestines! if you see a cat with string coming out of a cat's mout or butt take them to the vet immediately.
Fish waste typically appears as small, elongated, and dark-colored pellets or strands depending on the type of fish. The size and shape can also vary based on the fish's diet and health. Proper filtration and regular tank maintenance can help keep the water clean and reduce the visibility of fish waste in the aquarium.
Fish are piscine animals- Pisces- Fish. They do not have teats or breasts as they are not Mammals. Some fish are live-bearers,but they do no nourish their young, the small fry are dropped off like, well, a depth charge bay! Fish do not have breast nipples. Mermaids, if they did exist, would be Mammals, as they would have mammaries and also- mythologists miss the boat here, a mammalian tail like a Seal rather than a fish! this would probably be dappled like some types of Horse.
The fish is pooping.
i think it has to do with what they eat
That is most likely a string of feces hanging off of your goldfish. It will break off eventually.
If this is a white string dragging below the fishes tummy then it is poo (fecal matter). The fish could have constipation. Look to its diet and water quality fix whatever is wrong and the problem will go away. Remember Guppies are omnivourous, like their water around 70F. neutral pH and normal Gh and Kh.
It is probably poo. Clear poo in goldfish usually indicates intestinal parasites. Start the fish on a cycle of anti-parasitic medicated food.
the affect of the fish thing is like you can't even put a magnet on a fish so yea
fish like clown fish and all beatuifull and cool fish no sharks
humans only breath in air, and fish only breath in water. so a fish in air would be like you drowning in the water.
big with a lightbulb thing on its head
The fish is a type of animal though a fish is a type same thing like mammals. confusing but worth it.
It means that the thing which is being referred to is totally unnecessary, just like a bicycle is not needed by a fish.
Men are very competitive. They like to get compliments about how they catch the biggest fish or most fish. It's just a "man thing."
