Recommended Posts

Ok last week I had 2 angels die on me when i checked my ammonia and nitrate and nitrite levels my ammonia and nitrate levels were high so i did a 75% water change and it helped alot and since have been doing 25% water changes every 3 days my levels have been fine i even added a parasite medication after the 75% change well this week i have lost 5 sword tails and 1 cory cat and i cant figure why all levels are good and they looked healthy but then i either wake up or get home from work and I have a dead fish they dont look beat up they just died I currently have 1 sword tail 2 cory cats 4 bala sharks 6 zebra danios and 5 gold danios left and they look healthy as can be but im afraid I may have a silent killer please help any suggestions would help.

Hi bigdaddy. That was a lot of fish to put in a tank newly set up. I gather you did not "cycle" it first?

I believe a 29gal US is 36" x 12" x 18".

If it has only been going 8 weeks it should have started off with just the 6 zebra danios and perhaps, at the start of the second month you could have added the 5 other danios. No more fish than that until the filters had built up the good bacteria required.

Please read this link about cycling...

Bala sharks grow up to 14" and your tank is much too small for one, let alone 4. Please take them back to the shop. Juveniles can be raised in a 4ft tank but, to thrive, a 6ft plus is necessary.

Keep checking the ammonia, nitrite and nitrate levels and do water changes whenever they are higher than they should be. Although levels may be good now, as a result of the fish deaths so stocking level has dropped enough for the filter to cope, the fish may have been damaged due to the high readings and just taken a little longer to die than the others.
