I ordered 4 Harlequins to add to an existing school of 6 that I had already, but I am beginning to wonder if the 6 I originally had were actually Lambchop Rasbora, because they are much more orange in comparison to the new group, who are more of a pale orangey pink. Either way, the new 4 arrived healthy, just a little pale, and ate and explored right away - no dead on arrival and no deaths in first 2 weeks. Within a few days they seemed to have integrated into my existing group and eat voraciously with the others. Since they are still young and not fully colored, it's hard to tell if they are the same variety as the school they joined, but either way, they all seem to get along and school fine together so I am happy and hope they are too. Flip's shipping is always impeccable and I really appreciate their quarantine procedure so you know you are getting as healthy fish as possible. This is my third fish purchase and would use them again.
