Hmm- are those rainbow fish in the tank? Is you water more hard and alkaline, or soft and acidic. If the latter, the starlights will be fine, but I worry they won't do well in hard/alkaline water that the rainbows like. An alternative would be some line-bred bristlenose pleco, like an albino bn or some longfin bn (below are some link on aquabid to albino and "red" bn).
Another option may be L204 or flash pleco; they supposedly can do ok in slightly alkaline/hard water.
I think L52 (butterly) may be plant safe, but I'm not sure how it will do in slightly alkaline/hard water.
