Hi all,
Although I quit using live plants in my goldfish tanks, long ago, Here's my take on the whole concept of disinfecting plants for placing into fish tanks:
I think that disinfecting plants should be considered for what it is. It is for the safeguarding of our fish from parasites. Now, parasites have a very wide array of means of proliferation. Some have cystic or egg stages, some are born live. Yet others multiply by fission (splits into two). If one is to consider disinfecting a plant for parasites, they would have to take EVERY possible parasites life cycle into careful consideration before going about it.
A few facts:
Ich's life cycle has a cystic stage, in the gravel and wedged into plant tissues, that bleach, nor Potassium Permanganate, nor any other known (safe) product can touch. This cystic stage usually occurs for more than 2 days.
Dactylogyrus (flukes) lays eggs that cannot be touched by meds. Not even Praziquantel. This egg stage usually lasts for 3-4 days.
So, in knowing just those two facts above (there are more). One would surmise that a simple 30 second bath, a 30 minutes bath, or a 3 hour bath, would not be enough to purge everything that should be purged. So in the very least, there should be a bath, short quarentine for 4-5 days and then another bath before placing into a tank with fish.
Now, you might not like the results on the plants from baths, let alone two baths. But, most plants can and do grow back very well if pampered a bit afterwards. A small price to pay when it comes to the health of our fish. After all,
are the sterilizing baths for the plants or the fish?
Trust me, you don't want to have to battle with some of the baddies that are out there these days......
