corals staying open at night

[brybrybry]

ill try to get a pic of the crystal stuff by tomorrow. Might not be able to tonight. Well see. As for the tank. Its a 20gallon. No filter or skimmer. 6 months old. Approx 20lbs live rock. Fairly empty. (waiting for fraggg fesssst! To fill it hah). 1 algae blenny is all it has for fish. I do a w/c every day or 2.. Which might sound weird.. But its just 4L a time. Corals don't even react to it. Works great. Salinity 24 to 25 ish. Other params unsure. Don't have test kits.. But I bring water to the lfs every month and I'm always good. I guess the corals are just feeding at night, which would explain them staying open.

I also have a gbta and I feed it mysis shrimp 1-5 times a week.. I'm kinda experimenting with it... Seeing what it likes. ....

Go easy on feeding in a20g I feed my nem's twice tops and small amounts they also get food from light buy some test kits and find out forypur self what your parameters are I'm not sure shat they test for at lfs . I doubt water changes daily is beneficial to your system especially in a small tank by rights you should be doing 2g a week so not to stress everything out . Gsp, Kenya and most zoa's are pretty much indistructable

k so i checked it out closer tonight. dont got a camera right now, but ill get one if needed (i can just grab one from a friend). anyways they are more like thin clear tubes. Like a really small featherduster with nothing coming out of it.. and clear.
