VinceGill Posted December 30, 2020 Share Posted December 30, 2020 I recently moved all of my new thoroughly quarantined fish to my display tank. About a day/two days later 1 of 4 mollies had the white cottony muck around his eyes and a few spots on his body, also clamped fins. I treated with two days of a five day run of maracyn. My locals dont carry maracyn. He improved day one and looks/acts completely normal day 2. Currently awaiting a shipment of maracyn. Do i do nothing when it arrives if he still looks/acts healthy. Do I start a new 5 day treatment (I bought enough to treat my display tank, rather than my ten gallon QT/hospital tank. Supply on hand was appropriate for hospital tank. These fish were quarantined/med trio'd/and observed for 30+ days before moving to display tank). I'm assuming by the time i see 1 sick fish its too late to ahem, fish him out, and treat him separately - looking for guidance on this particular question. Tons of research has never really addressed this question. Its always how to treat/diagnose, never yes, remove the sick fish/no, its too late. So, when do you quarantine vs when do you treat the whole crowd? And, if you run out of antibiotics do you restart the recommended 5 day when supplies arrive or let it go if the fish are acting/looking/behaving/eating/pooing healthy? 30 gallons, 0 ammonia, 0 nitrite, 5 ppm nitrate, 7.6pH, 77F, many live plants, corys, tetras, mollies, 1 dwarf blue gourami, blue mystery snail. Thanks in advance to the smart, learned, generous, helpful folks who took the time to respond. Link to comment Share on other sites More sharing options...
Colu Posted December 30, 2020 Share Posted December 30, 2020 I would start another 5 day couse 1 Link to comment Share on other sites More sharing options...
Mitch_ScruffyCityAquatics Posted December 30, 2020 Share Posted December 30, 2020 Agree with @Colu . I believe the med’s box says to continue even if the fish start to look better. If you run out and have to get more, I would start over. It can be hard to get meds sometimes. I had to order Maracyn and Paracleanse from the Co-op a couple of weeks ago and they got them to me in under two days. As for the question on dosing the tank versus dosing a QT. I would move the fish to the QT for treatment unless you start to see the illness afflict other inhabitants. It can be costly to treat a display tank, but if you have a recurring problem I would treat all of the fish. Link to comment Share on other sites More sharing options...

Thank you for addressing quarantine. The other fish, including mollies showed no signs, but i feel like "it's in the water" more so than "it's in the fish" so assumed id be treating a quarantined fish and eventually tankmates anyway. Perhaps this is the wrong way of thinking. Treating in isolation is definitely more cost effective. I also worry about further stressing the sick fish with the net/transfer. Again, thank you for your insight. 1 Link to comment Share on other sites More sharing options...
quikv6 Posted December 31, 2020 Share Posted December 31, 2020 I think adding salt would also be a good idea, regardless of where you are in the treatments. Mollies take quite well to salt. Also, I have used it successfully on a platy with an issue that I believed to be columnaris. Good luck. Link to comment Share on other sites More sharing options...
VinceGill Posted December 31, 2020 Author Share Posted December 31, 2020 @quikv6 i have no experience using salt in a freshwater tank. Investigating in the past leads me to believe it may be detrimental to my live plants, snail and possibly my corys. Appreciate your feedback, regardless. Thank you. 1 Link to comment Share on other sites More sharing options...
quikv6 Posted December 31, 2020 Share Posted December 31, 2020 (edited) I think the plants will be fine with a very mild addition of salt. I have some plants (Hornwort, water sprite, guppy grass) that seem to have no negative effects from the salt I add it. I do a teaspoon per 5 gallons (very, very small amount) at each water change. I have mollies and platies. If I notice a fish isn't acting normally, or showing signs of something, I usually double t-to-triple that dose (still a very small amount), again with no ill-effects on the plants. I think you have a reasonable tolerance window to work with when it comes to plants and salt. I would start small, and see how it goes. You may notice positive results very soon, especially since you currently use none. As for snails/Cories....I have no experience there. Sorry.

Mitch_ScruffyCityAquatics Posted December 31, 2020 Share Posted December 31, 2020 Cories do fine with a small dose. I wouldn’t take them beyond 1 tbs per 2 gallon. The snails on the other hand will not tolerate it at all from what I understand. I would not salt the tank. I know many plants can tolerate a small amount of salt, but I have no idea which ones or how much. I only use salt in my QT tank. Here is a great blog on the use of salt for medication: Aquarium Salt: When and How to Use It Properly WWW.AQUARIUMCOOP.COM Should aquarium salt be used in freshwater tanks?

VinceGill Posted December 31, 2020 Author Share Posted December 31, 2020 This community is truly a wealth of information. Thank you all for your replies. Maracyn is nearly here. Everyone is looking healthy/behaving normally, including the sick mollie. I will run a new 5 day treatment. Again, thanks! 1 Link to comment Share on other sites More sharing options...
