isaly Posted November 21, 2021 Share Posted November 21, 2021 And I thought I might be okay after last week— I’m noticing that my biggest, most finned up serpae tetra is showing a little lightening of the tissue around its mouth and looking a little slack-jawed for lack of a better descriptor. Two died from columaris last week. Now there’s one more that looks like it’s following along—at this writing four out of twelve total I bought from lfs A remain (including the newly sick one). I’m starting from the idea that bad fish-keepers blame the fish store like bad craftspeople blaming their tools. I’m a newbie. I’m resigned to the fact that I’ll kill fish. This is the third serpae tetra that’s got columaris and will be the ninth out of twelve to have died since I first put four of them in on 9/8/21. The first died that night and two more the next day. Had no idea why. I got three replcements and two more for a total of six. A couple died for what I saw as no apparent cause. I got a few more. I can’t claim that I should’ve anything because I’m a newbie. I accept that maybe I should have done something, I know not what. Maybe it was just water parameters not matching. My pH was 7.1 by the API test. 0 ammonia, nitrite, nitrate, hardness 4/7 I used a little pH-Down to bring it to around 7. I didn’t think to ask what theirs were. My tank had been up for just a few days—was 'sterile' when I put ‘em in…just trying to cycle up with a few fish in and going slowly. I wondered what I might have done, or not. Maybe the shipper dropped ‘em or they got otherwise mishandled. Maybe it’s just one of those things that inevitably happens. I wondered about the store getting a weak shipment of fish for whatever reason. They were very willing to replace the ones that died at first and are nice people. I told myself that a bad fish keeper blames the fish store and, so, tried a few more to the tune of a total of twelve tetras…max serpae tetra population at any point was eight. Besides… There are four fruit/white tetras that are healthy and all in for fun. They’re living life…surfing on the current in the tank, tilting themselves slightly upward and obviously gliding as they ride the current around to the corner where the intake sits at the bottom and allow themselves to be carried around the corner to coast by the front of the glass. I love these guys. I have no quarantine/hospital tank. I could set up a five gallon naked hospital tank,100w heater, pump, and sponge filter I can’t justify right now treating them all with dosed food and water column. I guess I’d need to remove the plants, putting them in another container with a heater and dose the main tank water. Is this bacterium still in the tank? Will it remain there? Are any fish I introduce doomed, but the fruities……are okay… Is this something that’ll remain, hitting the weakest as I present ‘em? I don’t want to add a school of black neons to any tank of doom. Temp 76, pH 7.1, ammonia 0, nitrite 0, hardness 4/7, nitrate 10+/- by the way. Link to comment Share on other sites More sharing options...
