Hi guys, i bought 2 tomato clowns yesterday. i was very happy to see one of them was hosting my gbta when i woke up this morning. it seems she has some faint black marks on her sides? i dont know if i should be worried about this or not? i know i should of quarantined them, but they were the first fish additions to my tank. i dont know how well you can see it in the pictures. Any feedback would be appreciated.
