Strange corydoras behavior


Karen B.

Recommended Posts

My 7 false julii cory keep flashing in the sand. I saw some of my Chili Rasbora do the same so I treated with paracleanse. Problem solved for the rasboras but not the corydoras - they still do it occasionally. The treatment also left the water a bit white ish.

Today, they keep shooting up to gulp for air. I know it’s a normal behavior but they are doing it much more frequently. I have a sponge filter and good aeration.

And one of them keep hovering above ground but won’t settle. He just swim not erratic or anything but just won’t settle, sometimes just swimming in place, or pacing from side to side.

Yet others corydoras are breeding in the same tank.

It’s a community tank.

Population : 1 honey gourami, 5 otocinclus, 10 chili rasbora, 7 false julii cory, 4 nerita snails.
 
Cycled, planted, temp about 75, ph 6.6, kh 0, gh 300, 0/0/0
WC + gravel siphon every week or 2 weeks depending.
Filter is an aqueon hang on back quietflow 20.

Flukes. And they are becoming very resistant to meds. Dose Paracleanse per directions. I would dose 2 weeks, then 1 week off and then dose 1 more week.

I just treated them last week... (ended on friday). I should retreat them?

If they are still flashing, absolutely. I went through this nightmare scenario some time ago. 

I ended up dosing 4 weeks of PraziPro and another 3 weeks of Paracleanse to finally get rid of them.
