New Corys Seem Sad

[Gazoo]

Yes, those are crushed shells

I don't have a good pH testing kit, but I have one that comes in strips of paper that changes colour. It gives me a colour between 7 and 7.5

I was curious because I thought that shells would raise your pH to the upper end of the pH scale but yours doesn't seem all that high. I thought that might have been your problem with the corys but I guess it wasn't.

Even I'm quite surprised that my pH is not over 8, but I have been taking out handfuls of the gravel, and picking out the shells by hand....its hard work, but my parents won't let me change the substrate now I also have a diy CO2 system, maybe thats why the pH is controlled to some extent.

Edit: I've mentioned in some other post that I got my corys back from the LFS and they are doing very well now. I'm happy whatever the problem was, its now sorted out.

Hi akudewan

I'm glad you got your corys back and that they are doing better now.
