AbscessThis is a massive abscess. As you can see, the fish has a swollen head and reddening of the fins. This is a good indication that sepsis has started. An abscess must be caught early as large ones, as shown on this picture, nearly always lead to sepsis i.e. blood poisoning.

Sepsis in fishSepsis mostly only affects one fish in a collection at any one time. This condition is when bacteria - mostly gram negative - gain entry to the fishes body via wounds or through the gut wall. The bacteria can cause the failure of the internal organs.

Most symptoms show themselves as clamped fins, popeye, reddening of the belly or eroding fins.

In this type of cases the bacteria is inside the fish body and are unaffected by water born antibiotics such as ulcer cure (a load of rubbish!). Injection is the only form of treatment and is far better than adding antibiotics to food to the pond water. The latter in my opinion never works.

Sepsis in fishA fish with sepsis can look like its jumped out of the pond then jumped back in, and will be in a very poor state. If the disease is not caught in its early stages it will not respond to any treatment
