You have better chance posting in the sw forum. but to jump start. like mentioned above anemones needs very very good water conditions. they also need to be fed the fish will not provide nutrition for these animals. they need to be target fed krill or other meaty foods. also im assuming by nemo u mean false percula or true percula. different clowns prefer different anemones. if u have perculas they will do well with bubble tips, long tentacle anemones, sebae maybe , and true perculas given no other choice will even go for condylactus. anemones need very good lighting. single flourecent strip is not going to cut it. Theres more to it but ill let others chime in im no expert.
