i've put 2 baby and 1 adult female guppy into my saltwater tank. i acclimatised them VERY slowly, like a period of about 1 week. they are Absolutely fine. i just wondered if anybody else has had any success with this? and i was just wondering if there are any other species other than live-bearers which can be acclimatised into saltwater? i don't know why, but this aspect of fish keeping really interests me. thanks.
