I was preforming my weekly water changes, and I noticed something odd about one of my little guppies. One of my males (Mars), had what looked like a crook in his spine. I caught him in a cup and examined him with a light and magnifying glass. He has what looks like an "s" in is spine (not a super sharp one, but noticeable). I first thought it was TB, but I can't see how he could of caught it (isn't it also only a zebra danio disease?). My next guess was an injury.
The suspects for the injury theory are Mercury (the other male guppy), Sun Bane (my CAE), or Grell (a male rosy barb). Mercury and Mars often clash in battle and chase each other away from one side of the tank (which is pretty ridiculous because of how large the tank are and how small they are). Another suspect, Sun Bane, often rams into objects that are in her way (I sometimes see her shoving objects around), however, the guppies rarely (if ever) hang around the same area as Sun Bane. I think that the most likely suspect is Grell. The other day I watched him tailing a female and chasing off males. During this process, he almost crashed into a zebra danio and knocked over a guppy (I think that he is blind in one eye so he can be a tad clumsy).
One thing that scares me though is that I can't find one of my female guppies. I hope that this has to due with the fact that she is expecting to give birth soon but I also fear that a disease (that Mars might have) that could of killed her. I hoping I'll see her tomorrow. :/ (then again it is hard to find such a small fish in such a large tank.)
So my question, is there a disease that guppies can get that'll put a crook in their spine? (He acts as if it isn't there and hasn't changed his normal behavior at all). Should I remove him from the tank? (my quarantine tank isn't running right now so it'll have to be a jar or something)
One good piece of news is that one of my females finally gave birth and I found a small fry that I promptly named Pewee. :3
