I know that you all probably get very tired of me harping on this subject, but right now with the iridovirus and heaven knows what else, we are not sure that is all that is going on, we need to talk about quarantine again.
While the iridovirus so far has only seemed to affect Labyrinth organ type fishes, there is no saying that other fish who are kept in tanks with the Labyrinth organ type fishes in the
LFS cannot contract the virus as carriers and bring it into the tanks they are brought home to. So please do not feel that just because the fish you are bringing home and plopping into your tank is not one of the ones that is on the list to be infected with the virus, that you and your fish are safe to introduce them directly from the store to the community tank you have worked so hard to cultivate and grow. If they happen to carry the virus with them, and you have a healthy (so far) fish who is susceptible to the virus in your tank, you may be unleashing a horrible problem in your tank. Where if you put them in a quarantine tank for 30 days and they do not find a host to infect the virus is likely to die off and not hurt the other fish when they are introduced into the community.
This is no guarantee but at least you have given your fish a much better chance. Viruses are very hardy and very hard to understand but the fact is that during that 30 days you will have done several water changes and that fish will have a very good chance of losing its status as a carrier of the virus as the virus will have found no other fish to transfer to to propigate. This is the best possible way to try at least short of not purchasing any new fish to insure that you are not introducing any disease process to your tank. The only other way is to put one fish per tank in all the tanks you own and never let any of them come in contact with each other in any way but that is sometimes just not practical.
As it is in the hospitals, and after 27 years of being a nurse I know a little about this, the best way to keep from spreading virus infections is still good hygiene between tanks. Handwashing and sterilization and cleanliness and not cross contamination by using the same tools or products between tanks without cleaning them in a disinfectant first. Or better yet having a totally different set for each tank and never crossing from one tank to another. I have gone to using disposable cups to dip water out for each
water change instead of the syphon and tossing each one at the end of each change and not using it on another tank. I also use disposable gloves and throw them away between tanks and wash my hands between each tank.
Some of these processes take a bit longer to do but it is worth it in the long run as these fish are my friends and I have learned by personal experience that it is a painful thing to lose my friends. If it takes more time or even a little more expense, I guess my friends are worth it.
If you are not able to afford or do not have a quarantine tank or do not have room for one, a new plastic bucket with a heater and clean water can be used even if you do not filter it and do a 50% water change daily. I have done this. Just do not use one that has been used for any other purpose. I got a piece of plastic craft canvas to use for a lid so the fish cannot hop out and use an airstone to add oxygenation to the water and a heater and put a couple plastic plants and perhaps a small cave and I am set. They do quite well without light and just using daylight for the duration but I do have a small light I can use if needed that will attach to the bucket side with a clamp. I do not use gravel as it is easier to keep clean. The heater will not melt your bucket with the suction cups holding it away from the surface of the bucket. Believe me it works I have tried it. With a container of this size the water changes are not great and hard to do. There is not any excuse for not doing this and if you cannot afford to do it then you cannot afford to be buying more fish and adding them to your tank. It is simply too dangerous to your present fish.
Right now this is more important than it has ever been and it has always been important but this is vital now.
