About two to three months ago I purchased a small 2.5" diameter white BTA. I thought it may have been bleached but the price was right at 20$ and other than its lack of colour it looked healthy (mouth was shut nicely, tentacles were well expanded). Anyways, since I've gotten it, it has almost doubled in size as well as losing it's bubble tips, the tentacles are now about 3 times longer and completely uniform, it looks more like a LTA than anything. Also, it's colour has gone from a mostly white/green tinged to a pinkish with green hues. Has anyone else experienced this? What could be the cause?
