All my Serpae Tetras are sick. What to do

Hi there it looks likes fungal infection from that pic. Get a anti fungal fish medication and follow the dosing procedures. I would also add a little aquarium salt to the tank...usually helps calm the fish down.

I have to second cicrush13 here, looks like some kind of fungus. It is that large white thing that is in the center of the 2nd pic right?

I concur as well. I want to add that it may be difficult to medicate in the current set up, so if you have a hospital tank now would be a good time to use it. Watch the white spots closely. If any develop a red hue then you're looking at a secondary ulceration. At that point those are going to be the most expensive Serpeas you have ever seen.

Just one note, I detest Serpeas as they are aggressive fin nippers and bullys. When I first read the title to your post my first thought was say thank you! Anyway, the reason for the side comment is that pet stores sell these guys as community fish and they really are not. Kind of like tiger barbs, good when in the right place.

If Serpaes are given a high protein diet like betta food, for example, the fin nipping drops to almost zero. I still wouldn't trust them with a fish with long fins though.

As the issue has been raised in the last three posts, I will add my agreement. Serpae should never be in with sedate fish like angels, gourami, cichlids in general.

I have never come across the protein diet item before, that is interesting; but remember that too high protein is not good for most fish. I do know that keeping Serpae in large groups, 10+, can sometimes prevent nipping at least of some other tankmates...but again the angels etc are a real temptation and should not be included regardless. This just isn't fair to the fish; even if physical damage is not seen, the allomones these fish are releasing and other fish read are just as stressful.

I never had issues keeping mine with a shoal of angels in my 40 high. They kept to themselves.

Keep your airstone for oxygenation.
