For the most part...the clown has given up on the anemone and is hosting in a toadstool. The bta is in a crevice. Should I slowly adjust the rock to get him a little more light or work iit out on his own? Will the iodine supplementing help? TIA...truly!!!
IMO, you're trying to do too much. Stop adding iodine. That stuff can be very concentrated and you've probably got way too much in there now. Do you have a test kit for it?
I've had a GBTA for 4 years and 3 months. I've also used 4 T-5 bulbs the whole time. It has split twice. I can't remember the last time I fed it. It's just not needed. Once in a while a scrap falls into it or it will catch an amphipod, or one of my maroons will feed it. But I don't do anything special. Feeding them just makes them grow super fast which I don't want anymore because of space constraints.
In other words, I think you'd be best off just leaving it be. If there's something wrong with it, there's nothing you can do. Sometimes they will shrink up and move, but it shouldn't last longer than a day or so. If there's nothing wrong with it, it will survive on it's own.
IME, well water is not good. It's good that you have switched to RO/DI because it will eliminate a possible source of a problem.
What about temperature? Mine never drops below 79 and occasionally creeps up to 80. In the summer on rare occasions, it gets up to 84. It has never affected anything negatively though. Keep an eye on that if you're running out of stuff to rule out.
What are you checking SG with?
