They are a pretty unfortunate impulse buy. It's pretty important you read up on your purchase, pay special attention to nmonks posts: [URL="http/www.fishforums.net/index.php?showtopic=169129&st=0&p=1402389&#entry1402389"]http/www.fishforums.net/index.php?showto...p;#entry1402389[/URL] and [URL="http/www.fishforums.net/index.php?showtopic=169129&st=0&p=1405900&#entry1405900"]http/www.fishforums.net/index.php?showto...p;#entry1405900[/URL].dont know why but i saw these in my local shop,and in impulse i bought a couple ,i know they are filter feeders but can anybody tell me anything else about them ,are they usefull etc,cheers in advance.
Nope, they don't feed on 'nutrients' like plants or algae do, they just feed on very small particles of food like free floating algae and other plankton. Some people put them in their filters, but they aren't doing any good, they are just slowly killing the clams through starvation.Is it possible to stick one in your filter, so it can thrive from all the nutrients?
Pretty much, they bury in the sand/gravel and move around. Unless your tank has green water, they are very unlikely to be getting enough food. That means you are going to have to be hunting them down several times a week target feeding them using a pipette or syringe.I thought they were hard to keep alive, because it was hard to feed them, but I could be wrong.
