Hi all.

Not a great start to the day. Last night I decided I would add some blanched pumpkin to the tank to feed my bristlenose catfish. I usually stick with Zucchini but wanted to change it up a bit. Anyway I blanched it in a small bowl of just boiled water and then microwaved it in the water for 20 seconds (didn't really do much I know). I put it in the tank and when I woke this morning and checked on them all the rainbows were nose down tail up. They all had deep colours and what not and no damage to their bodies, no ripped fins, no redness or inflammation that I could see from looking over them once they were out. The only thing that's changed was the pumpkin. Their tankmates are 4 albino bristlenose and a big SAE. They were Coen River Trifas.

Now I know nothing I can do will bring them back but I just wanted to know why it happened. Does anybody have any insight so I can learn and help others in the future? I know I wont be trying pumpkin again that's for sure.

Thanks for your help in advance, Eric.

I wouldn't think there would be much difference in the boiled vs blanced, unless theres some sort of toxin or something that is deactivated when it's boiled the whole way through?

Bristlenose and SAE are fine, the SAE is skittish this morning but I think thats because he used to cruise about with the rainbows and now he's on his own.

Grubby, they were Coen River Trifas.

Surprising - rainbows are way tuffer than SAE .

Was thinking copper but the Bristle is ok ,

Yeah did water change right away and the tank always runs carbon. Im stumped and it annoys me that it happened for no obvious reason. At least if I knew I could avoid it and help others avoid it.

I have pumpkin in quite a few of my tanks a lot of the time without issue -

The sae are usually one of the first to go - if o2 is low they sit at the top 1 mm of water gasping .

It would take a lot of pumpkin to drop o2 levels low enough to be fatal Although that depends on load and tank size . I do not usually stock my tanks heavily .

I do not know how many rainbows in what size tank - but the OP did not give any indication of the tank being heavily stocked .

I think it was too after the feeding for an ammonia spike unless the tank was not properly cycled .

Its very oxygen intensive for microbes to break down pumpkin. The fact it liquifies when rotting or cooked means water column microbes multiply very rapidly in respose. What is called a dead zone event. The rainbows may have been first.... but likely sae and bn would have followed if it got worse.

Not a fan of cooking pumpkin or leaving it in longer than 24h.

What type of pumpkin?

They vary so very much.

I caused an epic peppermint bn wipe out with one of those grey skinned jap (also called kent) pumpkins.

I was given advice from a long time breeder not to use pumpkin because it fowles the tank and stick to zucinni/lettuce(remove within 24hrs).if you do use pumpkin,or even cucumber,remove it within a few hours to prevent these problems.Some fish are an exception because some fish wait for the veg's to break down before consuming them..experience comes at a cost
