Ive just lost 3 fish

fish are approx 50mm silvers

FT water flow is 200% of FT volume / hour
pH 7.2
ammonia 0
Nitrite .25
nitrate 40
water salted to 1ppt

Nothing has been added to this FT ie no weed or rocks or anything

Feed is the feed stu provided so thats almost certainly not an issue
Unless Ive over done it but I dont think I have. There is a chance foreign insects or frogs have gotten in but there are no signs of anything. I have on occasion found a frog and millipedes.

another fish was bent in half but I think that was more to do with being attached to the pump inlet

eyes are bright and gills look normal

there is a slight pink tinge on the tail underside. I'm not sure if this is normal for silvers. I hadnt noticed it before.

no sign of any fin rot.

all other fish seem fine

I'm trickling in my top-up water to do a partial water change (slowly - Im guessing at a rate of 1% of FT volume every 10 minutes)

any and all input greatly appreciated

please help

Hi BullwinkleII,

sorry about the fish, the water results look ok, what is the water temp? Small fish can die when the water temps get low over winter.

Is the pump covered so it cannot give you fish a big hicky? The fish with the injury looks like possible suction by pump.

God bless, froggo.

the pump inlet was very close to the bottom (ie less than a fish height - so they couldnt actually get under it) and is always on so I would have thought it was avoidable.


I just found these bubbles.

Slug slime or something?

I dont think that was there before. I guess it could just be caused by the dead fish.
The last time I looked at the fish was 2 pm today so they may have been dead for a few hours. One was still alive.

could that explain the vent rupture?

And the pink tinge ... is that normal. or at least normal for a dead fish?

One of the fish has grid lines on its side, would they match the strainer on your pump??

Yeah probably, but I cant be sure if they died and then fell into the pump. The pump inlet is very tight to the bottom of the tank, so I cant see how they could get stuck.

Ill put a further barrier to the inlet right now just in case.

the vent rupture is weird... never seen that :dontknow: . the pinkness I would think is just a post death thing? Lucky I ain't a fish expert :oops: See how they are looking tomorrow (the live ones :wink: ) forgot to ask your water source?

Hi BullwinkleII,

fish tend to go with the water flow. Water leaving the tank/pump inlet would be my bet as your water temp is good.

The fish may not fit the gap but it looks like they died being squashed and sucked into that gap.

I've lost many goldies from death by puree, it's amasing where they will try to squeeze into.

God bless, froggo

The bubbling is usually caused by protein from stressed fish, how long have they been in this tank, and any sudden temp / ph changes lately?

water source is rainwater from a concrete tank

ph is almost exactly the same as mine. Temp when they left here was 16, can't remember what day that was.

ok. well now there is a 20 cm exclusion zone in the form of a stack of that pot scrubber like form from the new pump for the other system still being built. so the foam is fish safe. ITs a big lump of that pot scrubber stuff thats brand new and came with a brand new pump.

oddly enough Ive actually seem something similar. When I had guppys ages ago I put a rock with green weed growing on it.. the fish ate it and ... kind of... burst. They looked a little like that.
