Have been having a few rough months around here.

~17" Murray cod, 2 years old, from Wes. I think killed by Malachite Green treatment I've conducted against some stubborn external parasites in both of my 4500 gal tanks. Used the usual ~3-5 ppm dose. Too much of a coincidence - had two cods eating exceptionally well and growing and both perished within a few weeks after MG treatment. This was the first time all the fish in both 4500's had ever seen Malachite Green. I try to turn to medications as a last resort only, especially as harsh as MG is. I've been told Methylene Blue is far milder and its killing spectrum is wider.

The other cod, ~18". The tail is damaged post mortum, likely by our 6 vulture catfishes.

~14" pike cichlid from Wes, also have had for 2 years. I got it old already but again this one died within a month after the MG treatment, so I tend to blame the treatment. The tummy is removed by vultures post mortum. That's their signature.

~15" 2 year old RTGG, the biggest of the three, same story with MG, I suppose, albeit its two brothers / sisters are still doing ok in the same tank.

~15" bowfin from snookn21, just got it a couple of months back, not sure what happened. It ate exceptionally well and got bold and started to claim the whole center of 4500 gal to itself. Could be MG again. Or not. Collected from the Everglades just before sold. Its brother at 14" still doing ok in the same 4500 gal.

My last Indian swamp eel at 22". Got them from Ray Chan at 14"-18" two years ago. Lost all 5 over the 2 years. One by one. None to an obvious reason. Some didn't feed well. Some did as this one... but still. Could they be short-lived? I doubt it. Something I wasn't doing right. Perhaps the diet of whole marine baitfish (they refused any pellets) is not right for them. The eye was taken out post mortum.

21" Pink GG, tattooed. Named Tatushka. Had it for 5 years. A second-time rescue with messed up snout due to having been kept in too small a tank by the original owner and sitting in a corner with its chin pressed against the glass. Again, maybe MG treatment that did it in. Can't be sure. Lost one more RRTGG (see above) but three others have been doing ok so far.100_7623.JPG 100_7626.JPG 100_7627.JPG 100_7628.JPG 100_7632.JPG 100_7633.JPG

~2' Yellowcheek from Wes. 2 year old. Had 5, now down to one. Been on a third try in 4500 gal. I missed the point of no return. It's been harassed too much. Removed it to another tank but too late. The last one is also 2' and is still swimming in the 4500 gal, coping with aggression ok, eating well.

~13" rescue Aluminum catfish. Had it for 6 years. Was mangled up badly by cichlids when I saved it. Tummy removed by vultures post mortum.

Sorry for your loss, those are pretty impressive specimens.

I am an imbecil when it comes to oxygen. I killed so many fish by suffocating or insufficient DO that I lost count. And I continue doing so. Here are the latest victims.

I missed how much wild fish grew in my temporary wild koi pond of ~20,000 gal. The wild bluegills and walking catfish probably doubled the bio-load of the pond, unseen to my eye over the years. I removed around 100-150 lbs of dead bluegills from the pond during this die off, each the size of a small frying pan.

Plus I missed how the flow of the only pump servicing the pond got reduced due to debris buildup.

Plus, I got 200 lbs of pellets for free and needed to use them up before they spoiled, so I overfed the pond for its current condition. If the prior two factors were not there, it'd be ok.

All this led to algae bloom and a bad DO deficit. Most of the 200 koi survived but ~30 perished, including my biggest 31"-er and my wife's favorite "ugliest colored" koi that has been with us for 10 years.

Man that is tragic. Something not often discussed is the difficulty of treating issues in a massive system with large specimens.

Thanks, mate. I can't think of a difference except I have to buy meds by a kilogram of 100% pure powder from Fishman Chemical. It just scales up. The best is of course to medicate with food, so the treatment is specific... which in this case was of course impossible as I needed to clear the whole system.

With Malachite Green, I made a mistake of not starting with a 1/4 or lesser dosage and verifying how ALL fish take it LONG TERM. I tried half dose and observed short term - a couple of weeks. All looked fine. So I gave them a full dose on the low side (dose recommendations vary) and even then all was fine short term but a few weeks later I saw what I saw.

I was thinking in terms of quantity and availability of meds, as well as the difficulty of controlling temperature for common stuff like ick. Filtering out the meds, etc.. But yeah I guess it is a scale thing but I would find it pretty daunting to treat 4,500 gallons of monster fish. Just hope everything smooths out from here for you. That had to be a real kick in the gut.
