Thanks for answering the questions. I see some things that we need to get a handle on to help your beardie. A lot of us came to this forum when we had some concerns and realized were were given a lot of bad info from either a pet store or somewhere else and couldn't believe the change in our beardies when we made some adjustments in their setup.
Your beardie is quite small for being 1 1/2 yrs old. But, being in a 11 gallon tank is too small for him. I suggest you check here to see if you can find a minimum of a 40 gallon breeder for a reasonable price.
http://www.craigslist.org/about/sites Tanks that small limit the amount of room they have to move around in and it's very hard to get the temps right which is extremely important for their total well being.
You mentioned that you have him on calci-sand which is actually very dangerous. Because it contains calcium, it encourages them to lick it then hardens in their bellies like cement. Another name for this substrate is "death sand" and it has unfortunately caused quite a few deaths because they get impacted and they aren't able to pass it. Rather than changing to alfalfa, I would recommend a solid substrate instead like
non-adhesive shelf liner, reptile carpet, slate tiles or if you really prefer to use sand, buy some children's playsand which isn't totally impaction free especially if you have a beardie that licks a lot, but it is much safer than any other type of sand or the other loose substrates.
I hate to be the bearer of more bad news, but the compact bulbs are also very dangerous. They cause all sorts of health issues, the main symptoms being lethargy and eye issues. You can read more about that here: [ Invalid URL Removed / p= t=65424 f=1 ] This is the best fluorescent UVB you can find in the U.S. For the hood, you can go to Walmart, Lowe's or Home Depot and buy a standard fluorescent light, remove the plastic cover and the bulb that comes with it, put in the UVB and leave the plastic cover off. You should be able to find a hood for $8.00 up.
You will need to use a basking bulb otherwise he will not be able to digest his food and he will get very ill if not worse. For a 11 gallon tank, you could try a 60 watt household light bulb and see how he reacts with that. BUT, you will need to invest in either a temperature gun or a digital thermometer with a long wire & probe end to find out what the temps really are. If his basking area brings him closer than 6" to that bulb, you should use a 40 watt instead until you can get a good reading of the temps.
I posted the link to the beautifuldragons site above, but here it is again.
http://www.beautifuldragons.503xtreme.com/Nutrition.html Please review it and offer some other greens/veggies besides just the romaine and carrots, suggestions would be collard, mustard greens, escarole, endive, etc. All the best greens are printed on that site in green ink. He should be fed fresh greens daily and can also get 50 small feeders (like crickets) or 30 to 35 larger feeders (like hornworms, silkworms, etc) a
week. They need protein and healthy greens to help them grow and since your beardie is only 12" he may do some more growing once you change some things around.
With an adult, you should be dusting his greens or live food 3 days a wk with calcium with D3 but phosphorus-free and with vitamins 1 to 2 days a wk. Since your beardie hasn't been getting any supplements, you could actually start giving him calcium 4 to 5 days a wk and vitamins 2 days a wk but you have to be sure you have a good
UVB light before doing it that often otherwise he won't be able to process it efficiently.
The romaine can cause runny poos so it would be a good idea to remove that from his diet and replace with others as explained above. I would also suggest that you take a fecal sample to a vet to check for parasites soon.
That's good that you gave him a
bath today, I suggest you do that at least 4 to 5 times a wk in case he is bound up from the sand. Be sure to put a washcloth down in the sink or container to help him feel more secure. You can add enough warm water (tested by the inside of your wrist, should feel warm but not hot or cold) to cover his front legs and he may even put his head down to get a drink. But, watch him closely because they can drown. A 15 to 20 min soak helps with proper
hydration.
I know this is a lot of information but I didn't want to leave anything out. One more thing about his eyes, the irritation could be from the compact UVB and/or from sand particles in his eyes. You can pick up some saline solution in your drug store, the type that is used to flush out the eyes and use that 2 to 3 times a day, that should help wash anything out and should also relieve the irritation from the compact bulb. Please be sure to turn off that bulb as no UVB is better for a few days instead of using that type.
If you have any questions, please let us know.
