When I started keeping fish, I would simply feed them tropical fish food and live food from the fish shop. But, after a while, I offered my fish a little cucumber and haven’t looked back. Here are some of the readily available alternative foods which I have given to my tropical freshwater fish:
Cucumber My fish like it best when peeled. I remove the very soft centre and slide a spoon through. This weighs the cucumber down to the bottom of the tank. To soften the cucumber, you can boil a large slice for 1 minute (if the slice is too narrow, it will fall apart).
Frozen peas These are much loved by my fish. I boil them, allow them to cool and removed the outer shell.
Romaine lettuce This is another food which my fish adore. I boil a leaf for 1 minute, allow it to cool and use a vegetable clip to attach it to the side of my tank.
Banana This is not so popular in my tank. I fed it raw and sliced but the fish were not very interested. Still, it’s always good to experiment. I understand that some fish love it.
Courgettes Slice, boil until soft, cool and serve.
Prawns These are very popular in my tank. I use fresh or defrosted prawns, remove the shell, chop up and rinse before offering it to my fish. It never lasts long!
Broccoli stem Slice, boil and cool.
Sprouts Boil and cool.
Remove foods from tank after 24hrs to avoid polluting.
