Hi Jamie;

I give my fish fruit sometimes too. I have offered bananas, apples and soft pears. I remove the seeds and give them the cores of pears and apples. As long as it isn't allowed to rot in there it's fine. Veggies last longer in the water though because they have a lot less natural sugar in them. I feed my fish spinach, romaine lettuce, cooked green beans, cooked and peeled peas. They are all necessary foods for many aquarium fish that are vegetarians.

The tank is just too small for angels. They all get to be over 4 inches in length and can be quite aggressive. The pet store is quite wrong about them not growing more. There are many color varieties and many fin shapes, but only one size of freshwater angel....Big. They should be in no tank smaller than 120 liters or so. If you add any other fish small enough for them to eat, they would certainly do it. Here is a profile page about them to see for yourself;

A siamese fighting fish should not be in with gouramis because they are in the same family. They would fight with each other.
