Put some of the food being fed to the crickets in their own enclosure into the reptile's enclosure so that the crickets have something to feed on if they themselves are not eaten right away. After hatching, however, food is no longer brought physiologically to the young and has to be actively sought in the outside environment. Fluorescent tubes supply a diffuse light with a low amount of visible light. Do not leave invertebrate prey, especially mealworms, kingworms, or crickets, in the enclosure with a reptile without also leaving food for the prey. Using a forceps hemostats or kitchen tongs, grasp the prey by the base of the tail and dangle it for the reptile. Because of the development of a neck….

After hatching, however, food is no longer brought physiologically to the young and has to be actively sought in the outside environment. Among the turtles, which have no teeth but are provided with a horny, sharp-edged beak which covers the jaws, the land species generally feed on plants or on small invertebrates mollusks, worms, and insects while the aquatic forms are omnivorous, eating vegetation while preying upon crustaceans, mollusks, worms, insects, fish, and larval amphibians.
Crocodilians are likewise aquatic; these carnivores have strong teeth implanted in shallow alveolae in the jaws. They catch their prey in the water or on the shores of lakes and rivers, mangling them with their sharp teeth and swallowing smaller creatures whole. Large prey is dragged to the bottom of the water, drowned while pieces of flesh are twisted off and bolted.
The teeth of the tuatara, snakes and many lizards are found in the upper and lower jaws and additionally often on the palatal bones, these are used exclusively for grasping the prey. Venomous snakes have specialized teeth for envenomating prey.
Opisthoglyphs, or rear-fanged snakes, have grooved teeth on the back of the upper jaw. These snakes cannot inject their prey by merely striking but must chew their victim to introduce the venom.
One drawback of mealworms is their thick, chitinous exoskeleton. Secondary to the difficulty in digesting these insects, overfeeding mealworms often causes regurgitation in herp pets.
Feed the worms to herps in moderation. Mealworms can be purchased in bulk and are easily maintained in a 5-gallon bucket. The substrate should consist of wheat bran, and moisture can be provided in the form of potatoes, carrots and occasional leafy, green vegetables. Again, remove uneaten food items to reduce the smell associated with culturing these insects. In the past 15 years or so, the king mealworm Zoophobias spp. These larger mealworms are popular because they are more conspicuous movers and often a more appropriate size for larger insectivorous reptiles.
Several companies offer cockroaches for insectivorous herps. These insects are easily reared in plastic tubs, and most of them do not require substrate. Like crickets, cockroaches require warmer temperatures for optimal production. Keep them at temperatures around 75 degrees.
Many species of cockroaches, such as lobster roaches Nauphoeta cinerea , can climb smooth surfaces, including glass, so extra precautions must be taken to ensure that the enclosure is escapeproof. Several products can be smeared along the top lip of the enclosure to prevent escape. Vaseline is the cheapest product to use. Simply place a 1- to 2-inch strip of Vaseline along the top of the enclosure.
A number of cockroach species do not climb glass. One such species is the orange-headed roach Eublaberus posticus. Although this species does attain a larger size, the instars the stage between molts are of an appropriate size for many species of lizards and frogs. Culturing cockroaches has significantly cut down on our monthly cricket bill, and despite our initial disgust at the thought of raising these insects in our home, they actually have a number of benefits over crickets.
These benefits include decreased odor production, a reduced chitin-to-meat ratio, and in some cases more conspicuous movement. Silk moth larvae Bombyx mori can also be acquired via several online resources. Vendors typically have them at reptile expos, as well. Silkworms can be maintained on a diet of mulberry leaves, and a mulberry leaf powder can be reconstituted to feed the worms during the winter months. A simple plastic container works well to maintain a group of these worms.
Depending on how much they are fed and the temperatures at which they are maintained, these worms can grow very quickly and to a large size. Keep them at a temperature range between 70 and 85 degrees, and they will do well. Mulberry leaves have a high mineral content, so silkworms make a nutritious food item and can be an excellent source of calcium.
Easily reared, they are relatively inexpensive if raised from a small size or egg. Like silkworms, tomato hornworms Manduca quinquemaculata can be picked up from a variety of online sources. However, do not use wild-caught tomato hornworms because these may be toxic to your insectivorous herp. Only purchase these worms from a vendor where you can be assured they were raised on a nontoxic diet and are safe for your herps to eat.
Tomato hornworms are sold in large deli cups with the appropriate food. In this setup they grow quickly and thus must be used in a timely manner, usually within a few weeks. Tomato hornworms weigh up to 12 grams, so they provide many more calories than crickets.
These worms are especially helpful for reptiles and amphibians that need to put on a little weight, such as anorexic animals, those that have been ill and are recovering, or those that are ready for breeding. A rodent colony can be extremely helpful in reducing the cost of maintaining a large group of snakes or large carnivorous lizards. Like culturing feeder insects, rodent husbandry is very important in ensuring a healthy food item for your captive.
The principle consideration when maintaining a rodent colony is cleanliness. Change the substrate at least once a week. Sometimes twice a week is better, such as during periods of heavy breeding. Rodent breeding typically slows down during the winter months, which can present a problem if you are feeding reptiles and amphibians that are active year round.
Plan accordingly and try to have a number of frozen food items during these months. You can purchase these or cull them from your livestock during periods of higher production. Another consideration in rodent production is the frequency in which producing adult mice should be culled. Ideally, older mice should be fed to pets roughly every two to four months. The final component to successful rodent maintenance is diet. Several companies manufacture rodent blocks specifically for mice, rats and other rodents.
Although costly, these food items ensure proper nutrition. Many people use dog food made in part with plant matter as a rodent diet. Dog food is less expensive and provides rodents with an adequate source of nutrition, but laboratory diets are considered ideal. Provide clean water on a continual basis by using gravity-feed water bottles. Mice often defecate or urinate in a water bowl, so change it often.
Just like gut loading crickets, a properly fed rodent provides nutrients to your herps for proper metabolism. This prevents feeders from harming the reptile and also reduces the amount of suffering by the food item. Even if you have the correct food item for your captive reptile or amphibian, occasionally animals will refuse to eat in captivity.
It may sound obvious, but certain species do not eat crickets or mealworms in the wild, and they may refuse to feed on these insects in captivity. Research the animal you are keeping. Find out what time of day it normally eats. If you feed a nocturnal species in the morning, it is unlikely to eat. Conversely, if you feed a diurnal lizard at night, it is not likely to eat. Perhaps a hide area is necessary, so the animals feel a sense of security.
Sometimes you can entice animals to eat by making their food smell like their desired prey. During the past 10 to 15 years, a lot of advancements in reptile nutrition have been made.
