hi guys
update
think my algae prob a bit better
maybe i am hallucinating
but it does seem better
betw 1-2 days ago, i notice there are some stuffs stuck to the walls of my fish tank
and i just saw my sea urchin eating those stuffs, on careful observation, i realise that there are small particles moving in the same zone, ie i mean that those small particles are from the stuffs stuck to the wall and the sea urchin is eating them!!
and i see a lot of small brown pellets thingy below the urchin and i saw those pellets being expelled from the urchin
1)can help me ID those stuffs on teh wall? looks like some spawn or sth
2)sea urchin shit so much???
