Do fish tanks need lids?

Fish tanks don’t need lids, strictly speaking, but having a lid can be beneficial. Lids help reduce evaporation, keep jumping fish in and protect them from falling objects, debris and curious pets. Lids can also help contain fish tank odor, so the room smells fresher. Choose a lid that is the correct size for your tank to ensure the safety of your fish and your family.

Should fish tanks be in sunlight?

Fish tanks should not be in sunlight, as sunlight can cause excessive tank heating and unwanted algae growth in your tank. Fish don’t need much natural light, and aquarium lighting can provide adequate lighting for your fish. Locate your tank in a quiet area away from drafts and direct sunlight.

Can a fish aquarium be too big?

A fish tank can’t be too big for your fish in most cases, but space, weight and maintenance considerations may dictate an ideal maximum size. Choose the largest aquarium that fits your space and maintenance limitations and be sure the stand and the floor will support the tank’s water-filled weight. Fish generally tend to do well in larger aquariums, and you can make your fish feel more at home in larger tanks with caves, plants and other places to hide. You do need to be careful not to get a tank that is too deep for your fish, however, as some fish, like bettas, may need a tank that is shallower so they can easily swim to the top.

Should aquarium tanks be filled to the top?

Fish tanks should not be filled to the top, or at least not all the way to the very top. Overfilling your tank can cause splashes or spray that may damage your floor and other objects nearby. It can also make it easier for fish that jump to leap out of the tank if you don’t have lid on your aquarium. A good level to shoot for is an inch and a half or two from the top, or up to the top trim line, if your aquarium features trim.
