Hi all, I bought two common clowns two weeks ago, both around an inch in size..... both seem to be thriving in their new home. However, one is slightly more pale in colour and slightly smaller..... but more worryingly, the white stripe above its head has a cracking effect covering the area just above its head. I have searched a few different forums but cant find anything specific......... easiest way to describe it..... it looks like someone has painted his stripe on and now as he is growing its cracking off. ( and before anyone says.... i have not been sold a goldfish with painted stripes!!!) like i say guys, behaviour is normal and all fish in the tank are fine.... its just the cracking im concerned about. Have tried taking a few pics but he wont sit still long enough for a close up!! Any ideas????
