I don't think the fish store will cover the loss but it doesn't hurt to ask.
the loaches are moving and hiding which are good signs. I did a 50% water change. I tell you what, the plants grew like crazy with the extra CO2. I guess the fish are more important to me.
I feel you. That is why I am going to my old method of growing plants in my 55. The fish are happier and that is the most important thing to me. Yeah, I love pearling - but what fun is it if the fish all die?
Have you thought about using Giant Danios now that you are back to fish selections? There are some interesting studies done on these and other danios. My favorite one is how they are ranked and the posturing they will do when coming across a higher ranking fish. They will actually "bow" to the more dominant fish. I was just reading this in a book I borrowed from the library. If you are interested, I'll send you the excerpt.
