the fruits i use are melons/banana/skinned grape/tomato and a tiny bit of lemon and orange but slightly rotting and very infrequantly (these fish can eat this but in very small quantity's and not very often and it has to be rotting) all this my giant gourami eats (nobody else gets a look in lol) plus a very wide range of other veg's and fishy meats he goes mental when i sit near the tank with a banana lol nose on glass and swaying his head and darting from one end to the other lol just like a dog
