I got diatoms and red slime algae-the diatoms are on the sand bed only-red slime on tanks back wall and on some zoas-WTH? Ever since I got my tail spot blenny my yellow rose prawn goby and pistol shrimp won't come out of their cave-especially the prawn he used to come out all the time-I hope they don't starve-I spot feed them but the bristle worms seem to get there first![]()
