Fin Rot

[hss]

two days ago i just bought a 7 inch florida gar from my LFS with 4 inch albino senegalus polypterus.. today i realize my gar suffer a fin rot alike disease.. i don't know where the disease come from.. my albino polypterus also start to have minor fin rot.. i have one polypterus ornatipinis in the tank before and he is still fine.. he stop eating from yesterday.. i feed him live shrimp and guppy.. and also some of the guppy feeder suffer the same disease today(in the feeder tank)

i just did 30% water change, bump up temp to 82F and add 1 teaspoon salt per 5 gallon.. anything i should do beside it? should i remove my ornatipinnis and treat only those two infected? is it really fin rot or feeder problem?
easy to recover?

looks like it could be partial ammonia burn, but also looks like a lot of mechanical damage...i would guess the ornate is attacking both fish as well (which they are known to do). i would separate the ornate from the rest of the bunch and continue your treatment. also do 50% water changes every other day instead of just the 30%...if you can do them every day that's even better. keep us posted; fins should heal up very quickly with this treatment (and likely with the ornate separation)--

Looks like fin rot. Treat with salt and Melafix. 2 weeks his tail should be grown back in.
Do this as long as your certain anoter fish isnt take bites out of him.

^no its not, meds also are a no no with gar. they tend to do more harm then good

that appears in my opinion to be damage from an attack. ammonia burn like sol said is a possiblity, but there appears to be no red in the fin, nor damage on the gar. its possible, he is the expert, but for the first time i think, i disagree that ammonia is even teh issue here. I personally put my money on it bein attacked. remove the aggressor, keep ur water clean and it will heal

edit* does appear that there is some ammonia burns possible. disregard earlier statement, though it bein attacked is the key problem here. do WC and keep ur water clean. no need even for salt here

thanks guys for the reply i do a ammonia test today 0 ammonia...
today i saw many small bubble peeling skin near his front body i guess. i thought gar is compatible with bichirs.. yes im able to seperate them for recovery.. but for the long term can they get along?
i'll change 50% water everyday for the next 10 days
before i start to work.. is it enough?
today picture update..

oh ya.. i have 2 feet x 1 feet x 1 feet gallon with only one 6 inch channa bleheri in it..
my gar now is in 3 feetx 1.5 feet x 1.5 feet
so at the time i have 2 tanks and 4 fish(7inch florida gars,6 inch channa bleheri,4 inch albino senegalus,8 inch polypt ornate.. what combination i have to try in these case? ornate to 2 feet tank and move the bleheris with gars and baby albino?
fyi 2 weeks ago when my bleheris in 1 tank with the ornate.. the bleheri suffer the same problem too + hitting the gravel.. but now he recover well in his tank alone..
my gar will be moved in 4-6months time...

Thats getting much worse than it was in the previous picture. Im not an expert on gar, but its either fin rot or Hes being eaten.
Id suggest a half dose of some antibiotic and also salt. Whether antibiotics are ok for gar i am not sure, but im sure salts are fine. good luck
* I dont think its ammonia.

Fish doesnt look well. Primary ingedient in melafix is tea tree extract so its pretty natural, Plus it wont harm your bio filtration. This looks like a secondary infection which will be difficult to heal on its own.
Somebody was saying meds arnt good for gar, but my opinion is to take action because that tail and that shaking doesnt look good.
