Yesterday I inherited 5 platy fry - they are about 6 weeks old and in good condition. I introduced them to my comminuty tank but have them housed in floating trap for the time being. How long before I should introduce them into the community tank? it is a 180litre aquarium (well planted) which contains 4 platies, 2 Giant Danios, 2 Clown Loach (6cm), 2 Oplaine Gouramis, 2 kribs and 2 Bronze Corys. I really don't want them to end up as food for the bigger fish....
