Running a M620 seio on one side of the tank directed to the top (as per what lfs told me to do) and the stock pump is on the other side. The lfs store's got a cube running the exact same way, and when it was running looked it ran great, apparently. (They took out the live things recently do to accidentally cutting a cuke, woops)
The tentacles do wave around as well. I can't get a picture as I only have a cam phone and web cam and it looks like an indeterminate blob on those (not enough megapixels). The clowns do not bother the frogspawn
at all. I don't think they recognize it as something to sit in. (They bug the one zoo alot

) Will recheck the temp with a different thermometer but I think the one in there is accurate. Temp drops a bit at night due to the fact the lights are what makes the tank's temp raise.
edit: Checked temperature with another thermometer and both thermometers are reading 80 right at this particular moment. Going to do a water change today of maybe 2 or 2.5 g to err on the side of caution.
Silly noob story of the day:
Gah I thought my 2nd clown was dead today as I could not see it anywhere. I glanced at the back chambers, then I moved EVERYTHING looking for them, probably upsetting it all and gees wouldn't you know it he was in the 2nd chamber of the back in like 1 cm of water and I just did not see him the first time! *bangshead* doh, lol
~~Looked in today and saw my first tiny bit of coralline algae growing on the outflow of the stock pump head today. (Only saying that because I think that is great)
