Angel sick? Help

lack of appetite, clenched fins, hmm appetite is pretty general but maybe a parasite he picked up?

Honestly I would put him in a hosp tank and treat w/ one of those tetra fizz tabs... I forget which one treats for clenched fins, I think its the parasitic one. But Any of the 3 treat a wide range of ailments and there may even be a "all in one" cure but its more expensive and idk how effective it is. All I know is every time Iv treated w/ one of those products I have had great results. But they seem to be relatively light on the fish (no seen stress for me) and may be the least expensive, safest way to do. That way if he gets better you know you got it but if he doesnt you can eliminate what your treating for.

Well potentially you could use a 5 gallon bucket but that would lead to other problems like no filtration, aeration, and you cant see the fish etc. The only other option you have is to treat the entire tank (what size). I am using maracyn 2 right now for columnaris and it does work seeminly but it is much more harsh than the other treatment and it is expensive. To fully treat my 75 gallon tank with JUST maracyn 2 would cost $42 and maracyn 1 is actually like a dollar more expensive... so if your tight on cash thats probably not the way to go. Its a tough decision to make to treat the tank and with what... but likely w/o intervention the angel will die. The first sign of onset in my tank was a Madagascar rainbowfish started to just hover for hours at a time in a mid-level location towards the back. If you can look at your fish when he poops, is it stringy and transparent ( mucus) or is it normal? If it is mucus than there is no doubt that you have an internal parasite and the clock is ticking. From my experience its about a 3-4 day time frame from onset in a fish to its death

and im all for additional opinions I try to get the most before I do anything as well unfortunately for w/e reason people dont respond to the sickness section a whole lot I have found... either because they dont know and dont want to be wrong or because they dont have sick fish and dont really care? But I feel ya

The tetra packs do 80 gals worth of treatment so you would be totally fine there, in such a small tank the other medication would me cheaper than for me, but it will still run you a pretty bill of about $20 or so (possibly more) tetra tabs are about $4 bucks for a packet of 8 tabs with 1 tab doing 10 gallons and normally they are a 1 treatment deal. Meaning you drop it in, let it dissolve (remove carbon) and you dont have to do anything else. This maracyn-2 (and 1 for that matter) you have to keep adding daily. 2 packets per gallon the 1st day and 1 packet a gallon for each day after that for a total of 5 days. Your better off treating the tank trust me, if he has it its in your water and possible someone else got it but reguardless the additional stress of moving on a fragile fish who is sick wont help him at all.
