    Yeah, I know. They are a pain in the butt. But they pay the bills to keep my server running. Just a fact of life, I am afraid.

    Is that too much for me to ask of you to keep this site running? Well, sorry about that. I too wish I could get everything for free. But alas.....

    Google Adsense ad revenue for December, 2025 was just $30 over the cost of the lease for the server running this site. So, in effect, the money providing the incentive for me to continue running this site is coming SOLELY from the paid memberships and sponsorships here. Which honestly ain't much....

Substrate for an Argentine B&W Tegu.

I live in Louisiana and was hoping someone could point me in the right direction in finding good substrate for a Tegu? I've read that cypress mulch is highly recommend. Any input would be appreciated.
 
Cypress Mulch is very commonly used and very commonly recommended by very experienced keepers and breeders.

You should show concern to ensure your Tegu does not eat any mulch that could cause impaction (intestinal blockage). This is true for any mulch though. The simplest way to deal with this concern is to feed them in an external feeding bin with no substrate. We personally feed in the main enclosure but on a large flat "rock" that is substrate free.

People often keep young Tegus on Coco fiber as it is much much smaller and less of a risk of causing impaction.
 
Around the middle of the second summer the average keeper should be able to tell the gender. Some breeders can very accurately sex them at a couple of weeks old but I have no clue how they tell.

The best way for us regular folk to sex them is to feel on either side of their cloaca (butt). Males will have what feels like a bb on either side. Females will not. I'll give you two guesses as to what these little balls are... :p

I suspected my male to be a female based on random speculation and guestimate comparisons. When he woke up from hibernation after his first winter I could not feel the little bb's. By mid summer I could. Around the same time he just started to develop fat jowls. At the end of summer his jowls were noticeable but not huge. Now, half way through his third summer, his big fat male Tegu jowls are unmistakable.

Their first summer they are tiny and adorable. Mine was around 16" when he went into hibernation...

Holy smokes! I couldn't believe how fast he grew his second summer. He went from 18" (May) to 40" (October) that summer putting on literally 1.5" per week for several weeks in a row.

This summer he hasn't been growing much in length (currently 46") but wow is he putting on weight. I haven't kept an accurate weight reading as he grows but he a bit over 9 lbs (4 kg or 4,000 g).

The best part though, he's sweet as honey. He hasn't once bitten anyone. My 6 year old niece can walk right up, scoop him up and play with him (her little friends think she's so tough when she does). He gets a bit of an attitude when it's time to come back in after free roaming in the yard, but besides that he's nothing but a big ole sweety.

I am firmly convinced that the keys are frequent (daily) human interaction coupled with a proper environment. I am thoroughly convinced that when kept in tight quarters the animal is constantly stressed which results in being constantly edgy. Aren't you a bit irritable when you are stressed? I know I am.

It's tough to supply them with a big enough enclosure, but if you can, I would recommend Tegus to anyone interested in reptiles. Mine is in an 8' x 3' @ 3.5' tall enclosure and spends several hours most days on a 10' x 6' outdoor balcony. He's spoiled rotten :p

It's almost scary as to how fast they grow. I plan on building a 8x4x4 enclosure this weekend. I was reading that it's not a good idea to place them in a large enclosure when there still young. Mine is around 16in long right now. Should I section off the enclosure??
 
I've heard that theory but I don't believe it...

I believe decor makes all the difference in the world. If the tank is 8' x 4' with nothing in it but mulch and a water bowl, the little guy will probably feel quite vulnerable and will be stressed.

But if he has a log or two, a few rocks, a couple hides... then I think he will absolutely love the 8' x 4' even as a hatchling.

I kept mine as a baby (I got him at 6 weeks old) in a 4' x 2' with a couple potted plants, a rock stack and a piece of driftwood. He did great. When mine was not much bigger than yours I put the same 4' x 2' cage on a 10' x 6' balcony/deck and left the cage open 24/7. Again the deck had plenty of 'decor' to allow him a few different safe areas along with plenty of space to move about.

Although, unless/until your Tegu actually wants to be handled/picked up... a 4' x 8' might make that part pretty difficult...
 
You'll have to do your homework on that one. Keep in mind Tegus will eat plant matter.

My suggestion is to shop locally and see what's available that you like the look of. Then copy down the latin name and google it.

The next step is to find a way protect it from the Tegu as they surely like to dig up plants. I'm currently toying with the idea now of building a wire mesh cage around the root ball and planting it. I may also build a sealed (with Drylok) wooden box with drain holes in the bottom to serve as the planter and put dowel rods in the top to keep the Tegu out. It's a game of trial and error...
 
Thanks again for the info!! I have yet another questions.... This time it's about lighting. I'm using a UVA/basking lamp and a 10.0 UVB coil bulb. I read some folks believe this is not enough. They are saying to use an MVB. What's your opinion?
 
Without doubt, UVB is required... But keep in mind where these animals come from. They are sub-tropical forest/prairie dwellers.

Desert reptiles will likely need a very high level of UVB. Tropical reptiles that hail from regions closer to the equator will need less than desert reptiles but will still need a good bit. But take note of where Argentina falls on the globe. Then to paint a clearer picture compare the northern to southern hemispheres and you will find that Argentina's range of latitude is not to far from the southern US States, with your area being closer to the warmer side of their range.

To put a bit of personal experience behind this theory... My Apartment has an upstairs balcony that my Tegu spends a lot of time on. It is common for him to bask in the early sunshine, but he avoids sunlight in the heat of the day like a vampire. He is active in the evening sun but rarely 'basks'.

I personally use standard incandescent bulbs for heat and a 4' HO UVB for a UV source. The key factor to using this approach is to ensure the fluorescent UVB lamp is close enough to the reptile. Being further than 12" from the animal renders the bulb almost useless for UVB.
 
Is there a such thing as too much UVA/UVB?? I just built my 8x4x4 enclosure for my B&W tegu. I'm using a solar glo MVB 160 watt by exo tera, a basking spot lamp and a 18" 10.0 UVB tube?? Over kill or what???
 
Sorry for the delayed response... and I finally made my own account :p

Yes there is a point of 'too much' UVB... but it's rare to reach it...

In desert reptiles I do not believe you can 'overdose' UVB at all... Likewise, it would be difficult to 'overdose' tropical animals...

But Argentina Tegus are 'sub-tropical'. So their UVB requirements are not quite as high as most tropical species, but it is still required.

The important part is to have UVB available in some areas, and not available in others. This allows your Tegu to regulate himself.

I personally like the flourescent bulbs more than the MVB. I have a 4' UVB bulb in an 8' enclosure which overlaps part of the basking area. This allows the tegu to bask in a heat lamp with or without UVB... and also allows him to bask in UVB with or without heat... as well as provides plenty of space without heat or UVB...

Reading up ont he subject will provide us with a wide range of very logical opinions and details, but in my opinion provide a range of options allows the animal to regulate itself within it's needs.
