Keeping and Breeding the Trinket Ratsnake Coelognathus helena

These snakes are a joy to keep. They are attractive, undemanding, breed readily, and feed eagerly. To the best of my knowledge, there are no new wild caught stock coming in, so these are a great breeding project to keep this species available for future hobbyist. I'll go into the details of how I keep them, but bare in mind there are probably many methods for successfully keeping and breeding this species.

As far as housing goes, I keep it fairly simple. They always have access to a moist hide box on the cool end and a dry hide box, too. I keep them in well ventilated tubs in the mid to upper 70s. Heat tape is used to create a small basking spot in the low 80s. I will turn the basking spot off if the room hits 80, but it rarely does as I set an air conditioner to the upper 70s during the summer months. Aspen seems to work as a substrate and I am sure paper would work fine, too. The moist hide box I feel is important to ensure proper shedding and because these snakes will generally lay several clutches per year.

Breeding is very simple. Feed them enough food items and pair them up on a regular basis. My adult male only eats hopper mice while the female will take several hoppers or a small adult mouse. I have not found any need to cool these snakes. The eggs take quite a while to hatch in the upper 70s to 80F but I generally get good hatching results During periods where I did not pair them up for an extended period, I have also gotten some infertile eggs so I wouldn't count too heavily on sperm retention alone. I have used vermiculite at 50/50 with water by weight.

The babies seem to prefer small live mice to start. If you're going to breed this species, I would plan on having a weekly supply of pinkies on the smaller side and then transitioning them over to f/t, but you may get lucky and have some that take f/t right away though I am confident you will have plenty that do not.

Dubia versus red runner roaches

With the rise of roaches as feeders, it can be confusing to know which roach species is best for your situation. Should you use dubia roaches or turkistan roaches? The species I am discussing here are Blatta lateralis and Blaptica dubia.   Will roaches infest your house? The first and most common question I get on these roaches is of course whether or not they will invest one's home. Unless your house is hot and covered in rotting food, I do not think the dubia roach poses any risk of infestation. Their life cycles are too long, they breed too slowly, and they are too poor at escaping to ever establish any kind of a infestation in a normal household. The Turkistan roach poses more of a question. They breed much faster, grow faster, and if there are places that they can get food and moisture, there is a chance they could infest your home. My gut instinct is that they also will not infest the average home but if your house is not kept clean, the odds probably go up that egg case...

Keeping and Breeding Oreocryptophis porphyraceus coxi (Thai red mountain ratsnake)

I have been keeping and breeding Oreocryptophis porphyraceus coxi for several years now. It is often listed as the Thai red mountain ratsnake or the Thai Bamboo ratsnake. This is one of the easiest species of snake to keep and breed provided you have an air conditioned house. They have great colors and are very hardy snakes but they really are heat sensitive and probably shouldn't be kept by people looking for a shoulder pet. I keep mine in 28 quart tubs in a rack without any supplemental heat. The colubrid room they stay in is between 75-78F year round. At these temperatures they will digest food without any additional heat. If you have an especially cold house, you may want to use some backheat to create a small spot in the upper 70s. Although I've never kept them warm enough to find out, it is reported that they may die if the temperature bumps into the 80s. I can confidently say they will do fine in the 70s. I use cypress as a substrate and keep the back half of the...

Keeping and Breeding Central American Banded Geckos (Coleonyx mitratus)

The Central American Banded geckos is a very fun species to keep. They are not a species for someone looking for a pet to handle, but they are ideal for someone looking for low maintenance pet where you can leave the weekend without worry or need for a pet sitter. They are very colorful lizards, although they do hide a fair amount. However, I enjoy seeing them come out and catch insects from time to time and of course there is some interaction during cleaning.  They also do not need a lot of space, a 10 or 20 gallon tank will work just fine for a single individual or a pair. I keep the breeding adults in 17x13 inch storage boxes with lots of ventilation holes drilled into them. I would not recommend anything smaller than this because you need room for a water bowl, a moist hide box, and a dry hide box, a cool side, and a warm side. I keep these geckos in a dedicated reptile room so ambient temperatures are in the mid to upper 70s and I provide them with a 3" section of h...
