Black spot
 
I noticed yesterday while doing a water change, a couple of my Red Rainbows have a black spot back by their tails. On one fish it's kind of oblong, the other is just a black dot maybe 1/16 to an 1/8th of an inch. The fish seem fine, the water perams are fine.. Did a couple of searches and found a few different answers. From lake spots to various other things. I know they were not there last week. Feeding NLS and spirulina flake.

Any thoughts on this, and should I be worried?

I wouldn't be concerned. Sometimes areas where there has been physical trauma can darken temporarily as well. Good clean water is all that is required IMO

Dont worry jim, is nothing to be concerned about. They are called "lake spots" even if the fish is not wild i have one nkonde like that, it doesnt affect the fish at all rather than the coloration of that spot in the tail region.

Possible "lake spot" ? I have heard that they are caused by poor water quality during shipping and that they sometimes go away, and sometimes they don't. Can you post a picture?

I read that as well, but these fish have been in there for well over a year, nitrates are sitting below 20ppm, ammonia 0 nitrites 0 I will try and get a pic but they are not very cooperative when it comes to that :LOL:

Hi Jim,
crazy, I've noticed the same thing on 3 of my Kasangas. My importer told me the Kasanga have come in that way before, and that they usually grow out of it.
It does seem to be way less obvious than 6 months ago.

I have had groups that had the spots also, they went away with improved filtration and larger water changes. They were f1 and had never been to the lake :D
It sounds like your water is perfectly fine. I would chalk it up to battle wounds also.

Yeah it's kinda strange, I only saw one with a black spot this morning. Go figure??

Was able to get a couple of pics, not very good but you can see the spots. Like I mentioned these guys are not cooperative in that dept :)

They seem to be clearing up. Sorry for the cloudy water I did a water change and a pretty good cleaning last night, I forgot to do the glass though :roll:

kind of a oblong spot on this one

Thanks for looking any ideas or have you seen it before

Hey Jim I noticed one of my RRs has almost the exact same mark in the same location. Mine are a bit younger and smaller than yours but it looks almost identical. Only 1 out of the 25 has the mark so I assumed it was a scratch from a rock or something. Not sure what it is but it doesn't seem to bother the fish at all.
