I had a red LTA just that color for several years. Unfortunately when I was out of town the heater raised the temperature to the 90s in the tank. I was devastated. I kept it along with a tomato clown in a 15 gallon tank for years. It was a male and spawned regularly. I kept it under two 55 watt compact PCs (this was over 10 years ago) and it did great. I kept in in about 5 inches of fine aragonite sand inside a 5 inch wide PVC piped that was capped at the bottom.
I hope yours does well. I would suggest you get it some sand into a tupperware/other inert container, so it can dig in. I can only imagine an LTA that isn't dug in will not be happy.
