I am thinking about getting a ten gallon (ca. 38 litres) aquarium so that I can add some Neon Tetras to my tank environment that already includes one Betta fish and nothing more. However, I noticed that the Neon Tetras and the Betta fish eat similar things. I don't want to waste money on an aquarium to hold more fish if it will be too much trouble to restrain my other Betta while the Tetras are eating! Is there a simple solution to feeding tank mates separately?
It depends on the type, size, and breed of your fish
How often should I feed the fish? How much should I feed my fish? These are common questions from novice fish hobbyists. Feeding fish can be fun, and it is an important part for keeping an aquarium. Many people think it is easy and there is nothing to it they need to learn. It is a false assumption. One of the top reasons for many fish dying in aquariums can be contributed to overfeeding. Overfeeding can cause serious problems including but not limited to polluting the water in the fish tank, stress the fish, or even directly kill the fish when their digestive systems couldn’t handle it.
Try sprinkling a small amount of food in the fish's tank and watch
PURCHASED LIVE FOODS
The live foods sold by local pet stores include feeder guppies and goldfish (discussed below), live adult brine shrimp (also discussed below), and black worms ( Lumbriculus variegatus ). Black worms are an annelid worm, related to both the earthworm and the tubifex worm (Tubifex tubifex). The tubifex worm is another worm that can be considered along with them since they are essentially identical in their aquarium characteristics. Both worms are aquatic but are found in very high nutrient bottoms. They are most often found in open sewers and therefore have a correspondingly bad reputation as disease carriers. Commercially sold black worms are however byproducts of the trout hatching industry, and so they are unlikely to give you something nasty like cholera. Black worms and tubifex worms were mentioned in the June 1998 issue of The Calquarium, where Steve Ward took a rather dim view on their use. I however have a less pessimistic opinion on them. I have in the past fed black worms to my cichlids about once every month or so, and have never seen any bacterial diseases as a result. They are also a very good food for bottom grubbing fish like Corydoras catfish and elephant noses (Gnathonemus petersi). In fact, one is hard pressed to keep elephant noses alive at all without a sand bottom and a steady supply of black worms. Cautions are in order however as black worms are very high in protein and fat, and so they cause problems if fed too often. The worms must be stored in the refrigerator with daily changes of cold water.
