My GBTA isn't white but it is light colored. I haven't had any GBTA's for a year and saw one so jumped on it. It has purple tips where all my others I had were just green. It was not under bright lighting as the guy keeps them in holding tanks. Has a company out of his house,and got the GBTA in and I bought it after two days of him having it. Added it to my tank and my 96watts let me see that its a light color.. Has a kinda white clear foot,with green here and there. pretty much the same with the whole body. Kinda see through all over. I have been trying to get it adjusted to my tank lights. 4-24watt T5 HO over a 30gal tank. It seems to like no lights or just the blue lights,when the days come on it acts unhappy. Water is good tested it,water also comes from the ocean,so did the sand. Marinelab filters/UV's water and gives it out to the public. It eats when I feed it but doesn't seem straving. I feed it shrimp,as thats what my other GBTA ate and they got huge. Dropped my lighting cycle down too 6hrs total. Whats the deal is he every going to come around? Going on a month now..
