Random fish deaths :(

trashion · 07-18-2008, 08:26 AM

I'm so sick of this! Every now and then, I wake up in the morning, look in the tank, and find another dead Aspidora. CO2 levels have been constant, no more fluctuations (this killed one or two in the beginning, a couple of months ago) But for some reason these fish are dropping like flies. No symptoms, water quality is fine: Ammonia 0, Nitrite 0, Nitrate 20. I do 30% water changes weekly. Any clues?

Maybe you just got a weak batch of corys.

Well, how old are they? If no other explanation can be found, perhaps its old age. I think the lifespan on them is like 5-6 years, but its possible.

I think you might be right, COM :\ I really like these little guys, too.

hacket- they're fairly young, when I bought them, they were tiny, around a half inch. Now the biggest one is about an inch. I got them only like, 3 months ago.

dont feel so bad, thats a common thing for aspidora, they arent the hardiest fish.

Yeah, but she knows what she's doing; that's a lot of death. How many did you start with?

**JustOneMore20** · 07-18-2008, 03:40 PM

Do you think your nitrates ever get higher than 20? I've had issues with more sensitive Cory species and nitrates around 40ish. Not considered high, but Cories didn't appreciate that reading.

**lohachata** · 07-18-2008, 04:22 PM

have you measured your co2 levels yet..many species of cories need high oxygen levels;and are pretty sensitive to any lack of DO in their environment.and check your DO also to see where it is at...

COM · 07-18-2008, 04:25 PM

I'm stumped. What is DO? Too short to google.

Dissolved oxygen???

**lohachata** · 07-18-2008, 07:03 PM

Dissolved Oxygen.....................

**lohachata** · 07-18-2008, 07:04 PM

good going com..

trashion · 07-18-2008, 09:42 PM

No, but I keep it at 1 bps, co2 indicator green.

COM: I started with 12 :\

COM · 07-19-2008, 08:24 AM

Yeah, I'd write it off as a weak bunch of fish. It's about time for another school of something small, though, so there is a bright side.

trashion · 07-19-2008, 11:49 AM

I might try to get them again, and see how that goes. I'm gonna beef up the Harlequins school, maybe up to 10 even. You've inspired me to push the limits a little, COM
