Tank
37 Gallon. 1x50g Aquaclear HOB and 1x30g Aquarclear HOB. 50g HOB has been on for over a year, 30g in last month (previous 20g backup filter quit).
Tank Mates:
6 Harlequin Raspboras, 8 neons, + Panda Corys.
Water parameters
Zero ammonia, zero nitrites, every few days nitrates are between 5ppm and 10ppm and I do a small water change (rather than 25% once per week, I am doing small changes 2-3 times per week equal to TOTAL about 30% per week). Temp. approximately 73 degrees.
Issue:
Panda Cory’s dying one by one.
Details:
Feb 19th added 8 pandas. Feb 22nd lost one. I saw one zipping all over the tank and when I glanced in an hour or so later one was dead – not sure if it was the same one. Feb 27th added three more pandas for a total of 10. March 7th & 8th – lost one more each day. Down to 8 (a total of three deceased). March 14th – one more deceased. March 15th – saw one that was healthy last week (despite missing an eye – I think he may have been that way when I got him?) was looking very thin and had stopped moving around much and by this morning he was dead as well. Total five deceased, six living.
I have observed that one cory is exceptionally pale and I keep expecting him die but he seems fine, and active. I have one cory who is 75% bigger than all the rest and I am almost wondering if this one is bullying the other fish?
I have observed that the neons are eating the sinking pellets that are meant for the pandas and that the raspboras have taken to ignoring their flake food in favour of hanging out near the bottom of the tank – they wait for the other fish to bite into the pellets and grab pieces as they break loose and float upwards. So, to compensate, I am feeding less flake food and more pellots and breaking the pellots in ½ before sinking them to give all the fish a better chance at finding them.
I am at a loss as to what to do. I love these little cory’s but I certainly don’t want to get more and have them die too….plus they are pretty hard to find around here.
Any ideas? Suggestions?
Now the pale one is not moving...
