Well, I just had my biggest nightmare. Came home yesterday and was feeding my fish. I noticed I couldnít see any fish anywhere in the tank except for one SAE who was lying in the front portion in the grassy fields. So I put some food in to attract them. No fish in sight. Food even falls right onto the SAE and he doesnít even move. But I can see heís breathing. So I start to look around to see what the heck was going on. I look behind and see some fish in the back but not really very active. Then I find my pleco dead.
Then I see my nice rainbow shark whoís not really doing much. I freak out! So I take out my test kits and start measuring.
HOLLY CRAP! PH is WAY out of wack. My low PH kit measures only a low of 6.0 But it was SOO bright yellow that I think it was WAY lower. At this point Iím really freaking out. Iíve had these fish for over 2 years in this nice 46gal tank with pressurized CO2. Iíve never had this problem. So I yank the top off, turn the CO2 off and drop an air stone in. But come onÖ 46gals at levels below 6. WTF are you supposed to do? I could do a massive water change but getting the water ready would take time. Honestly, the fish didnít look like theyíd last another five minutes.
Iíve got a second 36gal planted tank. Itís loaded with about 25 glass and neon tetras. I think about itÖ HumÖ Doesnít seem like a good idea to drop in >3Ē fish in with neons. But at this point I donít care. So in a desperate attempt to save them, I start yanking the fish one by one. Both thanks are at a similar in parameters (except for the low pH!!!). No time for them to get used to the water. Just grab the fish from the big tank into a bag and dump them into the 36 gal tank. It was so sad. I was actually able to just pick up my fish in the main tank and put them into the bag. When I would put them into the 36gal, they would just sink to the bottom upside down. So I grabbed them one by one and held them upside right into my hands in the new tank and helped them move around. They were burping CO2 bubbles!!! Slowly but surely, they started to have enough strength to stay upside right and swim away. Needless to say, they were very tired and didnít move much the entire evening.
This morning I woke up to find them nicely active. All are moving about as if it was all normal. Iím not sure what kind of damage this did to the fish and if my luck will change over the next couple of days. But I really really hope they make it!!!
It turns out my needle valve on the CO2 tank somehow got out of wack. It was almost a steady stream of CO2 coming out of it. This might have been happening for days now or even weeks.
So for now, half a dozen large fish are enjoy the company of 25 neons. Hopefully they donít develop an appetite for neons! Including my prized possession, a nice 4Ē rainbow shark.
On another note. Just wondering if anyone has any ideas of anything else I could do to help my fish recover? I'll have to keep an eye on the parameters of this 36gal tank cause that will be a HEAVY load onto it despite the fact it's planted. Other than that, I will be doing a massive water change into the bigger tank and waiting for a few days for it to settle. Thinking about moving my fish back into it this weekend. Is that too early given the trauma they just suffered?
Thanks for reading!
