bottom

I just got a blenny to try and help with some algae Issues and I am wondering if the sand has too much shell/rocks for the blenny. last week I took about about 1/4 of the old sand but I did not shift through the old shells and rocks. Should I do something for the bottom of the tank?

Just got 7 dispar anthias at least thats what i think they are the seller didn’t specify the species as they just called it rainbow fish or something. The seller said they were ‘old stock’ so they already ate pellets, i decided to grab them. They are being qted in a 70g now. They all are eating...

For brain coral, do you need to add a frag base before placing it on the sand? Or just place it directly on the sand

Has anyone had any luck (long/short term) with creating a false bottom out of epoxy/sand to reap the benefits of bare bottom while maintaining the look of sand?
