 My Notes on Argus Breeding

Years ago I kept monitors, and today I was feeling nostalgic so I came to this site to see how things are today. I am glad to see a few names I recognize and some I don’t. It looks like monitor husbandry is not practiced by as many people today. I can’t decide if that is a good thing or bad.
I used to post on here and other forums under the name DRZRIDER. I pulled up some of my old posts looking at how much I had learned over the years I kept monitors. Unfortunately I do not have any now, and a divorce a few years ago forced me sell the ones I used to have. For the sake of old times I included some rough notes I kept on a pair of Argus I used to keep. I also included some pictures at the end. I miss them!

Day 185
I checked on the baby and found it had escaped from the gladwrap and had wrapped the yolk sack around a bar in the shelf in the incubator. I unwrapped the sack to free the monitor and then put it in a sealed container.

Day 187
The yolk sack was attached to the baby by a small thread of skin and the baby could not move around without pulling the sack. The sack was hard and ruptured with the contents leaking out. I cut the thread of skin connecting the baby and sack.

Does everyone on here breed these varanids or do most keep them alone? I’ve been lurking around different sites, I find many people breed. Can’t one just keep a single monitor for the enjoyment of it? Do they live longer when bred? Nice information sir. Too bad you can’t get back into the hobby.

 My Notes on Argus Breeding

Fact is two monitors are too much financially for me. Just hope to raise the one I got into a healthy mature monitor. Iguannas and agamids are more social than the majority of varanidae. Maybe I’ll breed out my monitor, so it may have the experience, but two or more is just too much for me. Retes’ long explanation,Socratic like, makes sense but when you see a monitor in the wild they are generally going solo. They don’t care for their young nor express affection like monkeys. People who keep monkeys keep pairs, but the varanid mind is not close to as complex. I think people who keep more than one want to make money or are greedy, otherwise the extra space and food should scare new keepers off. Just imagine being stuck in your bedroom alone for life then one day a new person is added, so the space is now cut in half. I would go bannanas after the first day, especially if it’s a disagreeable woman, incompatible and aggressive, but stuck in the room forever. Good read but a little too sophisticated for the reptilian brain.

 My Notes on Argus Breeding


I’m not sure where to begin because you’re so wrong. Monitors are very social and do well in groups or pairs especially when raised together. You think those who keep pairs to breed are greedy? Are you nuts? Do you really think there’s money to be made breeding monitors? If so, give it try and let me know how it goes. The majority of people who breed monitors do it because they enjoy working with them so much. They also do it because they’d much rather support the hobby by producing captive born animals versus supporting the wild caught trade. There’s a real sense of accomplishment when eggs start hatching. I couldn’t imagine keeping a lone animal because I so enjoy observing the interaction of pairs/groups.

How many monitors have you observed in the wild? I’m guessing none? So, how do you come to your conclusion that they’re solitary animals. Maybe you’d prefer being locked in a room alone but I’ll take an occasionally bitchy female any day.

 My Notes on Argus Breeding

There isn’t real proof that monitors "need" to be with another monitor. Everyone should just appreciate the one they got and not keep adding more. Most varanids chase off other intruders when encountrered in their domain. You know this is true and correct, monitors are solitary with the exception of a few species. There are always examples to the contrary, but the majority are solitary. Frank cannot compare agamidae and iguanidae with varanids, just like comparing apples to oranges. One is neither good nor bad keeping reptiles, just interested and passionate. Going in circles, as retes puts it, about the need of affection is silly. Monitors brains aren’t as developed as primates or any social creatures because they do not have the range of social cues required to live in a group; with complex hierrarchy. Therefore their brains are no where near the same in structure as social creatures i.e. primates, dogs, parrots, and dolphins. Some people are animal hoarders and become too carried away with having one of each. You can at least see my point...Why else breed if not for money, are you going to care for a dozen or so new monitors? No, its simple you sell them for, in my opinion, way too much (especially dwarfs and tree monitors). Appreciation for the "one monitor" gets lost in our passion for all the variety, so we add and add to our little zoos. Maybe later I will introduce the opposite sex and see where it goes but for now we both will remain bachelors.

Define "real" proof. I’m guessing that you don’t have any experience keeping varanids, iguanas, or agamids? I’m guessing you haven’t spent time observing them in the wild? In other words, you’re making stuff up. You don’t think iguanas or agamids chase off rivals when they intrude on one another’s territory? All can be territorial and all are most certainly social.

So primates, dolphins, and parrots are examples of social animals because complex brain structures are necessary? Can you explain a school of fish?

No, I don’t see your point. And, believe it or not the vast majority don’t breed monitors for money.

Take a chill pill, relax man. You can’t say a monitor or any reptile has a brain as complex as a dolphin, primate, etc. They do have social structures, not nearly as complex as most social creatures. Where is your proof, field observations and literature? Take a break, eat a sandwich and relax. Go back to and circle jerk it with Franky. "Stop going in circles"....gosh

 My Notes on Argus Breeding

People who know they are wrong tend to over react to a simple discussion. Pointing the finger also suggests guilt or insecurity in what one actually knows to be true. You suggested that varanids need to have a companion for their psychological well being, but yet to show proof one way or the other that strengthens such an assertion. All I’m saying is varanids don’t necessarliy need to bond as a parrot or primate does in order to live a full happy and healthy life. Someone has been feeding you misinformation or you just feel sorry for the reptile and stick another lizard in out of your own guilt. I know V.salvator, V.niloticus, V.komodoensis do live in large groups and do have social cues, language and customs; they do not necessarily need to be bonded. More like cats, they have territory, breed, leave, and fight. Watch the show "Lizard Kings" with DR. Erick Piaka, pretty sure he doesn’t discuss the complex social structures of varanids. He dicusses the five orders of magnitude in the physical size difference of varanids. Not the intricate and complex web of social hierrarchy within the family of varinidae.

Stop putting words in my mouth. Where do I say they "need" to have a companion for their psychological well being? No one is feeding me misinformation, I speak from experience. I’ve kept and bred monitors for over 25 years. Your information comes from a TV show? Any actual experience keeping and breeding monitors besides your lone argus?

Charles if this is how you respond to keepers taking the time to give their long time experiences about a subject they’ve spent many hours studying in captivity and the wild, then I won’t bother trying to find answers to your question.

All I can say is you’ve been very rude.

If you have the experienced knowledge to start with why bother asking the question?? Frank has posted before about monitors in the wild been around in some form of social group other than komodo, 3240 has many years of experience in monitors & I’ve spent many hours over the years reading their postings in order to gain more knowledge that both FRank and 3240 and many others have posted, breeders of monitors breeding many generations of them.

If you have a backed up argument/ discussion about monitors social needs then post them with proof to back your findings up , like Frank did in the link I provided and has done in the past.

and i’m not one of his boy’s but I still respect what he has to say in the advancement and understanding of monitors in captivity.

You stated in your post that those who breed are greedy. Is that not an attack? One of the most ignorant posts I’ve ever read on a forum. Also, why do you assume I’m trying to enrich you?

You know for a fact they are solitary? No you don’t. You’ve simply read it somewhere but have observed nothing.

Number 3420,

Stating that people are greedy for owning too many reptiles is a fact, deal with it. In no way was it an attack on you, you are being way too sensitive. Are you usually this hostile with people or is it because you’re hiding behind the internet? I have observed monitors being solitary, its nothing uncommon. What is uncommon is a pack of monitors roaming Africa like hyenas looking for their next meal.

Charles Lee Ray,

How are greed and owning reptiles related? I have a group of lace monitors. Does that make me greedy? Please explain.

You know why you’ve observed monitors being solitary? Because that’s how you keep them. So an animal has to roam in a pack, like a hyena, in order to be considered social? Nice one. You keep referring to parrots as an example of a social animal. Do parrots hunt like hyenas?

I’m not hostile. I just don’t like you. Deal with it.
