Well, I have a sad story... and a question:
A couple months ago, I brought home some nice new angelfish. Unbeknownst to me, they had parasites, and within about a week or so, all fish were dead. All of em. By the time I realised what was happening, it was too late. I'm not totally sure what struck them, but I think it may have been velvet, or something similar. All the fish had tiny spots all over them - it sort of made them look like sandpaper. Very sad!
Fortunately, the snails did not seem to be affected by any of this.
So, if I were to try and re-establish some fish, is there any chance that the snails could be harboring parasites? As I mentioned before, the fish died off some time ago, and from what I've read, most parasites can't live very long without finding a host. Would it be safe to put these snails with new fish, or should I consider them "damaged goods" and keep them separate?
Well... at least I learned a couple of lessons from this:
1. Always use a quarantine tank w/ new fish.
2. Never buy from big chain stores (in this case, the angels came from Petco).
Lesson learned. The hard way.
