It's not been an easy road, I'll admit, but i'm on the downhill side and it's very satisfying.
I've solved the microbubble problem, turns out I am just an idiot on that one. I had the spraybar for the XP3 running directly above a bubble bar that produced very small bubbles. LOL - took out the bubble bar and the problem went away. Seems like such an obvious thing. haha how I didn't put 2 and 2 together, I dunno.
One of my original 3 rainbows developed some sort of fungus. She was QT'd and treated with Pimafix and Melafix, and it cleared up within about 4 days. I did 8 days of treatment with those.
2 days after she went into QT, my newest male rainbow developed signs of ich. Having nothing else to do with him, he had to go in the same QT tank. With the 2 rainbows in there, I slowly started raising the temps. A day or two later, my main tank began to break out with Ich as well. All of the rainbows, 1 of the rummy's, and 2 of the cories ended up showing signs, but I treated the whole tank and left the 2 'bows in QT.
I convinced myself the new male was the original carrier. He only survived about 2 days in the QT tank. Unfortunately having him with the fungus-wielding female she got the worse of the ich. She developed upwards of 30 spots at one point, as where all of the other fish only had 3-5 or so.
The Ich in the main tank cleared off pretty quick once the temps got up to 85, however the female in QT exhibited spots for many days longer. She remained in QT until all spots were gone, then was reintroduced into the main tank on March 1st. The main tank is still at 87-88 degrees, and will stay that way for another 2 weeks or so is my plan.
I've had several casualties throughout this past month. 2 Rummies were found dead against the filter intake. I originally assumed unknown causes, but the ich could have been affecting them and just not showing physical symptoms. I lost the newest male rainbow to ich, and 1 cory to it as well.
Things are better now, all the fish seem healthy and happy and doing ok. Even at the high temps, the colors in the rainbows have come back almost to normal, all the fish are eating and active.
Except 1. This just started a day or two ago, but one of the yoyos is freaking me out. I have 3, the 2 larger ones are extremely active and eat everything. Then there's the other 1. The past 2 days I'll find him laying on his side, breathing erratically. I've even found him laying on his back completely upside down. When I go up to him, sometimes he'll stay there, other times he'll turn over and swim off like nothing was ever wrong. He spends part of the day acting like this or hiding inside the wood cave, and the other part of the day swimming around, playing, eating, etc. I put in a slice of blanched zuccini last night, and he attacked it like it was going out of style. I don't know what to do with him, so for now I'm letting him be.
So that's been the past month. Nothing else will change until I'm done with the ich treatment, at which point I want to bring in 6 more rummies to give a school of 10, I want to try again to get a 2d male rainbow, and I still want that L066 pleco. So that's the future plans if everything goes well for the next few weeks.
YAY!!!
