    ive had my figure 8 puffer in this aquarium for about a month now and I just noticed these tiny creatures on the glass. What are they, are they dangerous and how do I get rid of them? Thanks!

    Picture #2 is a female cyclopoida. They're harmless!

    I am not too sure what picture number one is though.

    The first one is a planaria from what I know, and the second is a copepod. Both are harmless and good food for fish but the only reason they really pop up is because of overfeeding and excess nutrients. Water changes and vacuuming along with fish that eat them are really the only methods to lower their population. They're harmless and are actually beneficial to the breakdown of waste.
