Why are my black skirt tetras different from eachother? [Pics]
I have 6 Black Skirt tetras. 3 of them cycled my tank for about a month. The other 3 joined about a month and a half after the cycling started.
Here is what the first three look like:
Here is one of the first three next to one of the new ones (kinda blurry):
And this is what the newer ones look like:
Notice the fins. The older ones have mangy looking fins and they are longer. The new ones have nice perfect fins. Do they grow over time? The old ones' fins have almost doubled in size in just over a month...
Hi! I have heard that there are fancy/longfin black skirt tetras, and if there is such a thing it looks like your first 3 would certainly be it! I have black skirt tetras, but I've only had them for a few weeks so I wouldn't know if they grow over time, although it seems unlikely...
Quick question- Did your first tetras look just like your new tetras when you got them?
"Today, you can purchase a captive bred long-finned Black Skirt tetra variant as well as several colour variations."
That's an excerpt from this page: Black Skirt Tetra
All that really does is confirm the existence of long finned black skirt tetras.
Here's another site that has an article/description of them:
Blackskirt Hifin Tetra, Longfin Blackskirt Tetra, Gymnocorymbus ternetzi, Also known as Long-fin Black Widow or Longfinned Black Tetra
I don't know if we have one on here, otherwise I would direct you to that one and know that it is spam free and reliable *cough**cough* Thanks Byron *cough**cough*.
There are longfin varieties like Bobthesnail said. Looks like you have 3 longfin and 3 shortfin. When I bought my original 3 I too got longfin ones not knowing there was another kind but once I discovered this I made sure to get more longfinned ones since I like everything to match haha. Either way though they're the same species and completely compatible.
