Something is wrong with your water conditions/parameters. Do some regular water changes with good quality water of the correct parameters for guppies.
You can feed this fish by just adding smaller fish into tour tank. The amount is determined by how old it is. I feed mines 3 flag tales or ahole hole a week. i put all of them in the tank at ounce. and let the fish feed when it wants. When there is no more fish in your tank. YOU SIMPLY FUST DO IT AGAIN.
sick fish loose their color they swim less they hide they stay at the corner they stay at the top or bottom of the tank
It depends on the size of the tank and the species of fish that one is collecting. I can only give you a specific number if you can tell me the size of your tank.
The only fish you can keep in a 5 gallon tank is one betta (Siamese fighting fish) on it's own as that is a very small tank.
only if you clean it out
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.
dont put oil in your fish tank. the only things that should go in to your fish tank are things bought at the fish store. also insure you know what these products do and how to properly use them first
Only if you don't mind it eating the fish !
It is classed as a very small tank and could only house about 5 inches of fish. (1 goldfish is a 10 inch fish)
anyother fish, they only fight with each other
well it has to have light if you cover only the top it will be ok:o
they need a filter and i would only recoment a koi
