Dino Identification Help Please

[BasicBitz]

Hi everyone, just looking for some help regarding the identification of this (I think?) dinoflagellate. Am I correct in thinking small cell Amphidinium? Any tips on dealing with this? Seems to be mostly on rock/sand - this sample was pulled from the back of the display (area shown in the tank pic). Thanks in advance for any help here.
