Is that an injury to the gill? My Colombian tetras get whacked now and then and lose scales over the gill. They usually grow back unless they take a shot to the unprotected gills and die. Kribs are usually the hitters.
the only fish I have are kuhli loahces oto's and ember tetras
someone else also suggest that the fish in the pic was missing a gill plate
mine looks a lot like the pic but I cant see how it would lose its gill plate
I have literally no predators in there and all river rocks (rounded)
But I noticed today a second one may be showing signs of the same illness or w.e
weird thing is it is also on the left gill only that looks a bit too red, not as much as the initial tetra I posted about with the red swollen gil, but red enough to know it wasnt just the average "healthy blushing" gills are supposed to have
I don't think the temps were a problem. I keep my house at about 72-74 degrees and my 125g and 75g tanks don't have heaters. The temps stay pretty stable at around 75 degrees. I have oto's, tetra's, ram's, angel's and have never had a problem with them being at those temps. I don't use CO2, my Ph stays right at 6.6-6.8 ,Kh is usually 1 and Gh is about 13-14.
The gill inflammation could be from a parasite, as could the flashing from the oto's. Possibly gill flukes, watch your other fish and see if they develop the same symptoms. Go to where you bought them and look in the tanks for fish showing the same signs.
that was 74 in the day with t5 lights over them and a covered top. that being said the nights had to be much much colder. and I would also not think twice if it was 74 or even a lil colder, but it wasnt steady 74 Im sure
anyways the ember's gil looks a bit better and the rest seem to have nice body color so I dont think they are stressed, one or two are pale but all the rest look fine
even the one with the bright red gill isnt pale so that kinda baffles me.
do fish have a certain organ that is only on the left side of the body near the gills that could be infected or something causing only the left gill to swell?
kinda like how humans only have a heart on the left side.
something that is really messing with my head tho is I am having trouble telling if my other ember's are getting the same thing with their gills or if they just have a natural healthy pink to them like all gills should have. Im having trouble telling the difference probably because I am on high alert due to my other fish, there may be nothing wrong with the rest I just cant tell.
the one who is sick now kind of just sprang out of no where. it was like one minute he was fine the next he had a red gil, idk how it could of happened so fast so what Im thinking is it happened over night, I didnt notice it the next morning, left to get the heater came back installed it THEN i finally noticed and associated his gill with the heater in my mind.
point is I want to believe the rest fo the fish are fine because if it was the same illness the original ember had it should of showed up in a similar amount of time. one two days right?
today I did the treatment with melafix for my oto's but only at half dose just in case the meds are irritating the embers gills since it is 1% oil
after more research think I am going to go back to full dosage or 75% at least
I added an extra airstone and now I am just waiting. to see how they all end up. I thought about just stopping the melafix all together but it seems to be helping the oto's I think. Since I fixed the initial problem (broken heater) I almost just wanna stop treating and see if they get better on their own, just not sure if that is smart.
one thing I have been thinking of past few days is when my heater broke down, i grabbed another old one from the closet and bleached it then rinsed it off thoroughly(at least I thought) and used it for the rest of that night, the next morning was the day I got the new heater AND saw the red gill.
could this be a chemical burn? and if so why did it not burn the entire school of fish?
since this originally happened ive done about 3 pwc's
one 25% and two 15%
IF this is a chemical burn should I add some carbon to the filter?
I haven't yet because f the meds I am using BUT like I asked previously if I shouldnt be treating with melafix anyways since there is a gil issue in my tank, I should probably add carbon forsure right?
just not sure if i should add it WHILE i am using the meds
ok done ranting, thanks to anyone who took the two yrs out of their life to read this post
