SO I jsut got my SAEs today.. they will sit at the bottem and maybe eat some algea then they will swim up against the glss back and forth and up and down then do sit and eat more algea and swim around the medium hieght of the tank for a bit and then do the glass rubbign again... what is up?
My ammonia levels are 0 nitrite is 0 and nitrAte is 5 ish.

how long till they actually start cleanning hair algea? and how sencitivy are they.. i had an ammoia spike of 0.25 but I knocked it back down with prime.. no nitrIte spike yet. 
the rest seem fine.. I dunno if they are crazy or eatting the algea.. theya re hanging out near the algea wall alot..
