Hi, I know you posted this on our forum, but I feel it may be better to respond here. As this is more about you then the monitors.
Your monitor is screaming something is wrong and you keep saying, but they have "this and that" hmmmm a list of instructions. Like that means nothing should be wrong.
You must understand, caresheets, or a list of instructions, is no more then a guide to the possible positive outcome. It does not mean its a sure thing. I know, with simple reptiles like colubrids, following instructions can normally lead to success. But unfortunately, these ain't them. Monitors are GREAT fun, because they keep us on our toes. In fact, snakes are so boring(no mental challange) I will fail from falling asleep. The key adjustments for them is so few and far between, I can lose interest. With monitors, you HAVE to make key decisions, nearly everyday. Why I am saying this is, I hope you never expect to have them run on their own.
To me, many of you treat monitors like building a model airplane/car/boat/ship. Most follow instructions and if you do that the model will be build. If you do a good job, the model will look nice. If not, parts may be in the wrong place, glue drips will be here or there, decals may be in the wrong place. Then there are model builders that make models that actually work. Here the instructions tell you how to put the model together. But you still have to learn to fly/drive/sail it. Of course, the instructions will offer a basic guide on how to operate the model. But you still have to learn how to operate it. In most cases, newbies will indeed crash their model. Even smart newbies. This means, you should expect to have problems with your monitors.
ALso, even those with the experienced, they will eventually crash their models, the reason is, they just have to test the limits of the darn thing. The result is often the same, but at least the experienced ones got to operate the model for a longer time.
I know, I hate analogies too, but talking about monitors does not work as most do not WANT to understand, they are not so smart. You see, being smart with monitors IS making the right decisions, at the right time. And understanding what is actually happening.
In this case, you have a glue drip. There is a problem, even though you used glue just like the instructions said. BUT the question is, did you use that glue correctly??????? Obviously you did not. As you have a problem. Do you get that? Just because you followed instructions, DOES NOT MEAN YOU FOLLOWED THEM CORRECTLY. Only with monitors, what tells you that you followed instructions correctly is, LACK OF PROBLEMS. following them incorrectly means problems.
For instance, Cypress mulch, who the heck told you(gave you instructions) to use that. And next, what the heck is topsoil????? I would guess in most cases, topsoil is not what your looking for. I think topsoil is rich dirt that folks who grow plants are looking for. What monitors like, is that crappy soil from the desert that only cactus will grow in. As in, not rich, not topsoil. Ackies are a arid land monitor. They do not occur where there is TOPSOIL. But sadly, I cannot say that the soil is what caused your problem.
To offer a base to understand monitors. When exposed to things that are not suitable, they do not roll over dead. What they do is stress out(internally) and the immune system becomes compromised. Then they fall to any old common antigen(bad thing). Again I cannot say this is what is causing your problem. The reality is, a healthy monitor can heal from huge gaping wounds in a couple days. A unhealthy monitor develops problems without help(injury). What is the problem here is, you think feeding means something. Well with snakes, they will stop feeding, when something is wrong. With monitors, they feed up until and sometimes after they are DEAD. Monitors do not die, they have to be murdered, stomped, killed. They do not go easily.
Also temps, who told you 130F for a hot spot. Let me remind you, I am the fool who started this hotspot thing. And I never recomended 130F. I believe I say the MINIMUM is around 135F. I always offer more then that. But that is OK. Below that, problems can increase. Of course there are all sorts of combinations that will allow the use of lower temps. But unfortunately, below 135F means, you need to be experienced. And know these combinations. As in, 135F or more, allows you to not have to know so much. For instance, its not the hotspot thats important, its the range of temps in the surrounding areas that are IMPORTANT.
So all this bull beans comes down to this, a reoccuring problem means something is wrong, no ifs, ands or buts. What is it? heck if I know, I am not there. But it appears to be a stress induced immune system problem. Or maybe a splinter from the dang cypress mulch(cypress mulch is full of splinters) Cheers
