Aquariums are usually less costly, as well. Dogs and cats require regular visits to the veterinarian, vaccinations, flea and tick medications, etc. Last year the purchase of pet toys was a billion dollar industry. We don't have to worry about buying a tug rope or a stuffed friend for our fish. An aquarium is less of a commitment than larger pets, and can still be a welcome addition to the family home. Use plastic or rubber scrubbers, rather than metal to clean the sides of an acrylic tank. Be careful not to accidentally pick up a piece of substrate or gravel while cleaning the inside of the tank. However, if you do happen to scratch an acrylic aquarium, all is not lost. The tank can be repaired, unlike glass. This is usually the same set up and water balance you will use to house other fish as well, so it should not be a major concern when you add your catfish. Catfish are known to be somewhat goofy and comical, but this may depend on the species of catfish you have. Their behavior will vary, but as a whole, the catfish is an entertaining addition to an aquarium. Feed only a small amount that can be consumed within the first two to five minutes. Over feeding is a common mistake among novice fish keepers. Any excess food should be lifted with a net if possible, as it will become debris and quickly dirty the tank. Water should be kept regulated and tested weekly. They same store will also carry any solutions necessary to adjust the P. H. There is not much wiggle room when it comes to these specific staring points. In order to avoid a costly mistake it is important to be patient, watch the tank closely, and make sure that you don't introduce any marine life until the tank is absolutely ready. If you are using a live plant that is primarily a stem plant, try to remove the lower leaves. These low leaves tend to not get the amount of light needed to remain healthy. The use of live plants will definitely help in creating a masterpiece aquarium that is pleasing to the eye and is a happy and healthy environment for your fish.
