bubbletip not so bubbly anymore

[Nihoa]

this question has likely been asked previously but a quick search didnt yield anything. when our green bta was small the tentacles were squat and bulbous but now that it has grown the tentacles are much more elongated. we added a large rbta as well and it too has more elongated tentacles. does this happen as these anemones grow? i have seen btas in other peoples tanks where the tentacles are really thin and stringy, not the case with ours. our have fat tentacles, just not short and bulby.

they are well fed, mix of raw shrimp, squid and scallop every second day or so. they are in moderate flow and under 160 watts of t5 lighting. water parameters have been steady. any thoughts?
