My endi's are unusally active! Since the start of this particular tank, I have had ornates (very active), Delhezi (always the docile one), and endi's (the newest addition). The tank has yeilded great growth results! Now that I have parted with the ornates, the endi's have become the largest, dominent, and now most active. UBER-ACTIVE! Is there cause for alarm, or is this behavior normal? Poly's are usually calm and lethargic. None of my dominent poly species in this tank have been. Believe me, I enjoy their antic's in the sand and constant swimming, however... what's up?
