10g low-budget diy nano reef

[Nevin]

Hi all,

I've been keeping an eye on several varieties of algae that came with one of my rocks. I'd be much obliged if anyone can help me ID them, or at least tell me whether they're likely to become "pests" and overgrow everything. Number 1 are red stalks about 1/4" long.



Numbers 2-5 are easier to see. 2 and 4 might be the same.



I could probably start adding a cleanup crew at this point, if anyone has snails/hermits available for cheap?

Thanks,
Nevin
