I bought these for my fish when I first got into fishkeeping to give them a varied diet. For a while the tubifex was ok, fish were enjoying it and no problems.
A little while later though I started to encounter some problems with fish dying from something internal. Wasn't sure if it was the food or not though, so carried on feeding every now and then.
Fed a tubifex cube again and one of my glowlight tetras started to spin around in circles and had no balance, eventually it died and had a hole in its stomach. By this point I was getting convinced that it was the food.
I left feeding tubifex for a little while and had no problems in the mean time.
Decided to feed tubifex once more, again another glowlight tetra span around in circles and had a hole in its stomach at the end.
After the last incident the tubifex went in the bin and since have had no problems. After research it turns out tubifex feeds on sewage and this food needs to be prepared properly in order to kill parasites and bad bacteria etc.
If you are going to vary your fishes diet, the best way is home-cultured live food, specially treated frozen foods, flakes or deshelled cooked peas (broken into small pieces).
