BTA Split!

[Magma]

So our BTA moved today for the first time like 3 months and he went into a corner, became nice and small and we left to do some shopping etc. come home and now i can see 2 feet and looks like hes tearing himself apart in the middle.

should i be giving it any special care now? I did a PWC this morning before I noticed him moving today and all my levels seem great.

I notice one half looks really stringy and ugly
