Alright, we got new Bettas and we've had them for four days now and two of them have been displaying odd symptoms that aren't really lining up with anything we've read on- and we've read on everything.
First we have our currently unnamed fish, he's been darting around the tank erratically but he doesn't seem to be trying to rub himself on anything. Nothing seems to set him off, he just does it. It almost looks like he's trying to jump, which we've been told is because of a water problem. But we've also been told that Betta just jump.
They are both in a half-gallon split tank [It's temporary, we haven't gotten their real tanks set up yet.] and the splitter has holes, so they share the water. We changed their water 100% yesterday because they didn't like the flakes we gave them, so it muddied up the water. They were fine before that. I'd like to mention that we forgot to put Aquarium salts in this water [My roommate changed it so I wasn't paying attention] but our third in a seperate tank has had no ill effects.
Would it be safe to change their water again, maybe 50%, and replace it with Aquarium Salted water with PH leveler, Stresscoat+, and anti-bacterial solution MELAFIX [less than 1/32nd of a tablespoon in the one gallon of treated water] or what?
I have a video of their behavior, Pangur Ban, the other Betta, is behaving normally, though he has a little something on his bum. He had a poo that was dragging the other day for several hours, and then today he had a little fuzzy whit bit on his bum. My roommate said it looked "pointed" this morning, but I never saw it. The fuzz is still slightly there, but it's either dropped or been rubbed off over the course of the day. We've very, very scared it might be fungus because we lost a fish to that last week because we didn't catch it early enough.
I'm not sure if I can upload a video, but my fish is erratically darting around his tank, then he'll slow down and sit near the surface and just sit there for a while, then he'll go back to darting.
We're thinking of treating the whole tank with Quick Cure, but since it's a half gallon we're still not sure how to give them the proper dosage because it calls for one drop per gallon. Suggestions on how we should take care of this? We're worried he might have very early ICK or Velvet, and we want to catch it now.
Since they share water, we want to treat them both. The tank that they're in is our half-gallon hospital tank, but we haven't gotten their proper tanks yet and we're testing their behaviors for a possible community tank with other types of fish later.
Please help, we're incredibly worried that something is happening to them. MY roommate has confirmed that it appears to her than my nameless darter fish is trying to rub his FACE on things, but not any other part of his body. She says that his face looks odd in comparison to the rest of his body; "raw" is the word she used, like he had scrubbed it raw. The scales are perfectly fine, but his face just looks like a person having rubbed their face raw. In which case, he had this when we got him!
Anyway, I just got information that Pangur's pointed bum is a symptom that another user had with their fish and they died from it; from feeding them black worms. We have not fed them the worms in three days. I'd like to rehash that his little bum is back to normal.
And, one more thing we're also worried about; our third that we bought at the same time we got the other two, is Crum Cruach, and he's got a thin black rim around the edge of his fins. We can't tell if his fins are getting smaller, we don't THINK so, it really really doesn't look like it, but we've seen photos of fin rot and the outline of the fins is black. Here's some photos of him the day we got him:
And here is today:
Also, here is the nameless fish:
The day we got him.
