Fish can sometimes become very territorial, try moving the item to a different location in the tank.
The Xiphophorus helleri known also as swordtail is one of the impressive fish among the livebearers. Its tail look like a sword, his native color was metal green but today we can see swordtails in many varieties such as green, orange, yellow and the most common is the red swordtail. It requires 10 gallon tank and up, even though they can handle themselves with other fish don't keep them with tropical fish big enough to eat them, weekly water changes are needed, will appreciate plants as a hiding places in their tank.
Your swordtail is probably dead. Remove him before he goes rotten and poisons the water. I hope you are observing the basic fish keeping rules which state :- 1 inch of fish needs a minimum of 1 gallon of water. :- Every tank needs a permanently running cycled filter. :- Every tank need at least 50% of its water changed every week.. Follow those rules and your fish stand a chance of survival. Fail to follow those rules and I can guarantee failure.
Get a separate tank for the goldfish (or swordtail either or) these fish are naturally not compatible and putting them together endangers the lives and overall well-being of both fish. If you keep them together much longer the goldfish will probably be wounded by the swordtail, get an infection, and die. Hope this helps
Depends on type of fish, how long the fish has been in that tank and the occupants of the tank. Some fish stay hidden till either night or feeding. A newly introduced fish will stay hidden normally until it settles in. If other fish have newly been introduced there could be a power struggle and the fish that remains hidden could either be guarding it's territory or being bullied. It is possible if it had eggs that it is guarding them. The behavior you describe does leave that possibility open.
If the tank's large enough, just leave them in there. Red wag swordtails are peaceful community fish. Otherwise, you have four choices: get another aquarium give them to your friends sell them to a pet store do what my buddy who breeds Bettas does with the imperfect ones, and give them to your Oscar. (Oscars are a necessary part of any fine fish breeding program.)
Fish can disappear in a fish tank due to hiding in decorations or plants, being eaten by other fish, or jumping out of the tank.
Goldfish bowls are not suitable for keeping any fish in and all fish need to have their water filtered properly with a cycled filter. The basic rules for keeping any kind of fish successfully are :- 1 inch of fish needs a minimum of 1 gallon of water. :- Every tank needs a permanently running cycled filter. :- Every tank need at least 50% of its water changed every week. Follow and keep to the above rules and your fish stand a chance of survival. Fail to keep them and I can guarantee that your fish will be constantly getting ill and maybe dying.
Hold the fish down and throw out of tank
it depends on how big it is if it is a goldfish or beta it can be in a bowl.If it is one of those big tiger fish or aqarium fish then put it in a big tank. A fish will grow to the size of the tank or bowl. For instance, say a goldfish is in a tank, it will not grow as big as the tank; however it will grow big enough to be able to swim in their environment. The fish will not overgrow the tank. I had a six inch goldfish in a thirty gallon tank.
That depends on what you mean to say. For example, if you have one angel fish in the tank you could say "That's the fish's tank" meaning that is the tank for the angel fish. If you also had a couple of clown fish, you could refer to the tank as belonging to all three fish by saying "That's the fishes' tank." Slightly different spelling and punctuation
They need to be kept separated from other fish until they are too large to be eaten. You also may need to keep the basic rule in mind too. The basic rules for keeping fish successfully are :- 1 inch of fish needs at least 1 gallon of water. :- Every tank needs a permanently running cycled filter. :- Every tank need at least 50% of its water replaced every week.. If you follow the above rules your fish will stand a chance of surviving. If you fail in any of them I can guarantee that your fish will be constantly getting sick.
Yes, but depending on how big you or the tank is.
