Okay Nick, you came here looking for advice, and you're obviously not getting the help you need (with the exception of a few posters like Mike). So, I will do my best.
Now, this post may seem a little direct, but I’m trying to help you, so don’t go off and flame me or something like that.
Your iguanas are SICK, especially Espio. They are malnourished, dehydrated, and look as though they are developing metabolic bone disease. They WILL die if you don’t make drastic changes in your husbandry.
I know you’re getting people like SkyLineGTR posting a lot of “I told you so” crap. This is NON CONSTRUCTIVE guys!!! If you’re not going to try and help this kid, stop wasting everyone’s time. And Nick, don’t post back to them, it only fuels their narcissistic little fire.
Please, listen to what I say, and do it. You need to make changes and you need to make them now. You need to be very careful who you accept information from on the internet, for example, SkyLineGTR looks like he needs a little bit of help of his own.
The first thing you need to do is separate the two iguanas. Although they may appear to get along, I highly doubt it’s a healthy environment for them to be in. They will be stressed out by being together. If I were in your situation, I’d put them in totally different rooms where they can’t even see each other to minimize stress as much as possible. Building two separate cages will be expensive, but has to be done. The MINIMUM dimensions are 6ft x 3ft x 6ft. Bigger is better.
Next, diet! Go to a grocery store. Buy as many of these as you can: Collard greens, dandelion greens, mustard greens, turnip greens, butternut squash, buttercup squash, kabocha squash, acorn squash, snow peas, sweet potato, green beans, and bell peppers. This is NOT a complete list, just a few suggestions. Wash everything, and cut them into very small pieces. Feed as many greens as you can, your iguanas need calcium. Let them eat as much as they can. Make sure there is a lot of water on the food, as your babies are dehydrated as well. Offer them food several times a day to maximize the likelihood of them eating. Variety is key, research and find what are acceptable foods and provide as many of the best foods as possible at all times. NO ANIMAL PROTEIN.
Lighting and heating is EXTREMLY important. If your iguanas do not have an overall temperature of 85ºF, they aren’t warm enough to complete essential bodily functions (such as digestion) properly. They need to have a basking spot of around 93ºF in addition to the rest of the cage so that they can thermo regulate themselves. Not just any light will do. They need to have a UVB light (such as a PowerSun, T-Rex, Zoomed, etc) that is made for iguanas. Stay away from things that say “full spectrum”, or ones that don’t say “UVB”. Vitalites suck, don’t get one of those. Without one of these lights, your iguanas will not be able to process any of the calcium from their meals, and their MBD will continue to progress. You can buy heat lights and UVB lights in one (like a PowerSun) but this will not be enough heat. Buy a ceramic heating element to get your temperatures up. Make sure you set these up in such a way that the iguana cannot burn themselves.
They need to be kept HUMID. Mist them very frequently, or add a humidifier to each of their cages, bath them every day, let them play in your shower while it is running. Iguanas are TROPICAL animals, and low humidity will take a toll on their bodies. Try to keep each cage at 60-80% at all times. Provide a water dish in each cage.
Take them both to a vet, but not just any vet. Do your research, contact a nearby reptile association and find the name of a REPUTABLE and certified exotic vet that has experience and training in treating iguanas. The vet will be able to give you lots of advice on how to try and turn your iguanas around and make them healthy.
Keeping two iguanas healthy and happy takes a LOT of money and time. Especially to get them set up. I recommend adopting one of the two out so that you can put all your time, money, and effort into turning one of your iguanas into a happy, and healthy animal.
Here is a list of sites that you NEED to read and understand:
www.greenigsociety.org
www.geocities.com/ig_chick/igdex.html (look at the diet information)
www.myiguana.com
Buy “Iguanas for Dummies” by Melissa Kaplan (although some of her information is questionable, the majority of that book will help you), as well as “The Ultimate Owner’s Manual” by James W. Hatfield III (this is an excellent book that will teach you a great deal).
If you think this is too much time, or that it’s too expensive, do what is best for those animals who are completely at your mercy and give them to someone who can dedicate themselves to the iguanas. But, if you’re willing and mature enough to do everything in your power to make them as healthy and happy as possible, by all means do so and continue coming to this forum to ask questions. Don't be afraid to ask your parents for help, once they see that you're honestly trying to do this right, they will help you. Do as much research as you possibly can. I researched for two years before getting my iguana, and I still research all the time, and learn new things.
Again, I can’t stress enough how much bad information is given over the Internet, on this forum and in websites. Chances are, if you only read something once on one website that doesn’t really coincide with anything else you’ve heard, it’s wrong. Read, read, READ! There is a LOT to iguanas, and you have to take on the responsibility of learning it.
If you don’t want to post on this forum because of people and their ridiculous little power struggles, feel free to email me privately and I will try my best to help you as much as I can.
This post was a very small, general overview of iguana care, but I hope it will be enough to help you off your feet.
Please, I beg of you, read those websites, learn as much as you can, and get back to me.
