lol !! some flatworm exit or a velvet sea slug, but since my husband doesn't want me to use "quemicals" in the tank i guess i'll just keep admiring them or may be someday i'll get lucky and my LFS would get one of those slugs.
What do you think about the hang on Prizm skimmer from Red Sea. for a nano? worth buying it or not?
Sorry i just gotta know how long is this one gonna last me for my 37 gal tank
