BTA Split so soon...?

[OCDP]

Well I got back from Maui (which was amazing) to a nice dirty tank... I guess my tank-sitter must have just simply fed them and left ... he also knocked out my stop time pin on my light timer... meaning (for however long it was out) the whtie lights were on 24/7 ... so that pretty much left me with a 20g box of algae. Got it all cleaned... took forever... end of story. As I was picking up a rock to clean it I felt a lot of mushy material under my hand... and to my suprise, it was a BTA clone! Thsi BTA has only been in my tank for a month.. maybe one month and a week .... I am wondering if there si anything I need to do for the BTA now? they look okay... the clone wandered around a lot.. but has now got comfy in a spot. They both ate shrimp last night, but are being kind of picky.

Any reasons as to why they split? Still new to the anemone thing and did not suspect a split to happen this soon! Especially with such a small BTA to begin with.

TIA,
Scott
