So it has just occur to me but I believe Ciroc may have fin rot.
First, because I rescued him from walmart and knowing their reputation I wouldn't be surprised.
Secondly, he does have black tips on his tail.
I can't really get any close up pictures [ but I can try if need be]
But I have a strong feeling this is it.
For those of you with some high knowledge of this please give me some advice or suggestions on what to do and help me verify if this is it or not.
He isn't lethargy at all, he eats, and is very active. The only problem are his fins. [tips are black]
Here is the closest pic of him I have at the moment.
