Idk y but lately all I'm into is my clean up crew and what fish can clean my tank I always like to ask you guys cause u guys give great advice so what do u guys suggest
sand sifting stars are great if you have a 100+ gallon tank and lots of room for them to move around to search for detritus. otherwise best to leave them alone and use snails.
My Fighting Conch does a great job in my 30g. Nassarius (as Custom05Taco mentioned) work well too. There are also Hector's or Rainfordi Gobies that sift the sand but they can be tough as well.
