Also noticed this hitchhiker astra starfish. I know some people think of them as pests but I've never had problems with them so I'm leaving him in.
Also noticed that my tank seems to go down to 75 at night (and its not that cold yet) so I'm going to have to figure out some sort of heater soon. Unless.....dwarf seahorse maybe???? Not sure if the tank is big enough for one or not.....also not sure if I can keep such a small tank stable enough for one. I'll have to do some reading.
