One of the keys to a happy and thriving pet fish is a properly fed pet fish, whether a damselfish, angelfish or Siamese fighting fish. Fish are all different, however, and what may be suitable for one may not be suitable -- or nutritious -- for another.
Damselfish readily consume plant and animal foods alike, and herbivore-based sustenance can be a strong addition to their diets, adding both amino acids and vitamins. Look for commercially available frozen herbivorous food that consists of an array of beneficial, herbivore-friendly components, such as algae and vegetables like carrots, peas and broccoli. Always consult a veterinarian before you begin feeding your damselfish anything new at all.
Commercially manufactured dried flake foods can also help establish a well-rounded and nutritious damselfish diet plan. Seek out a flake formula that caters to fish such as damselfish, lionfish and clown fish. Always make sure the commercial food you purchase is suitable specifically for damselfish by inquiring with a veterinarian and closely reading product labeling.
Algae is yet another common meal staple for many damselfish. Some damselfish readily munch on the algae available in their living environments, although algae flakes from fish supply retailers also can work well in their diets. Seek out a protein- and mineral-packed algae flake formula to supplement the rest of the diverse and omnivorous meal plan.
Meat, Meat, Meat
As classic omnivores, damselfish do not shy away from meat and happily accept a wide assortment. Mysis shrimp, fish eggs and finely diced seafood all can be welcome elements of a proper damselfish diet. Meaty frozen foods like cut-up squid pieces also can be a success. Out in their natural environments, damselfish often gravitate toward meals such as shrimp, plankton and other tiny marine organisms. Never give your damselfish any frozen food item unless it has been totally thawed. In terms of portion, avoid overfeeding and only offer your fish an amount of food that he can handle fully eating within a span of three to five minutes -- no more than that.
