Fat fishies - obesity as a health risk?

  • We are currently upgrading MFK. thanks! -neo
Most fish will just let surplus food pass through them (and wreck havoc on your wather) undigested. There are, however, the risk that you are feeding your fish the wrong sort of food -eg. to high fat, animal protein or what have you, for your type of fish. In a comunity tank this is a rather big issue. And the wrong type can lead to enlarged liver or (dont remember the english word) "that the food stops inside the colon/stomach". This can bloat fishes. So I would try to give them some other types of food -read up on what they eat in the wild and try to mimic that.

For my fishes I feed them pices of thawed or fresh fish bits, or diffrent types of frozen insects, or vegetables like squash, cucumber and the likes. Flake or pellets are a once a week thing -if even that.

(sorry for bad english but Im tired ;) )
 
Goldfish lack stomachs, so maybe the excess relatively unprocessed/undigested waste from over feeding built up to toxic levels, throwing your water params out of wack, and killing your fish in turn.

there are quite a few fishes that lacks stomachs and have a rather intricate colon system instead. But they do have livers that, for goldfishes, have problems coping with to much fish or animal proteins and fat.

So I dont think you can make your fishes too fat (you can offcourse feed them to the max but not in human terms as fishes dont store fat as we do) but you can bloat them with unhealthy/wrong food.

In others words (I hope my son and my better half reads this ;) -would suprise me tho...) keeping, as I do, a goldfish with discus aint a good idea! Better explain that... Ive got some goldfish and koi's stocked away in my garage for the winther but my 5 year old (on his own) went out there and caught a goldfish and took it inside and put it into my discus tank... And there it has stayed this winther. He has grown enourmously and his colours are great but I fear the long term effects on him...

I forgot to include the problem of digesting proteins, thanks for mentioning that. As far as making fish too fat, I think it is possible, as well as the fact that by over feeding, you can cause a fish (certain ones are more prone than others) to develop hepatic lipidosis, which in turn can mean death.
 
feed algea spirulina flake for a staple diet add other veggies and feed protein 2x a week
 
In the past I had texas cichlids 2 seperate times that litterally ate themselves to death. I stoped buying that type of fish.
