Good lord. Well, as already stated, you are outrageously overstock. IMO a 150g tank isn't even big enough for just that arowana alone!
If I understand correctly all you feed them is frozen seafood and feeder fish? Well don't worry about being overstocked. Most of them probably won't live much longer in an overstocked environment that likely has sky rocket levels of nitrates and them not getting all the proper dietary nutrients they need. Pellets are made for a reason. They contain all the vital nutrients are fish friends need to live a long happy live. Feeding them nothing but feeders and frozen seafood is going to be depriving them of crucial dietary nutrients they need to live long and be healthy. So if you're running out of money to feed them it's because you don't have them on a quality staple food you can buy in large amounts for relatively cheap and keep buying them feeders and seafood. I can see why you're running out of money!
If you just keep feeding them what they want they'll never eat pellets... You need to train some fish to eat pellets.
EDIT: Wow, got like four responses while I was typing. Yeah ^ ^ mfk marketplace. I didn't think anyone existed in my neck of the woods and I had no problem finding a good home for my sailfin pleco that I didn't want to house permanently. If you really want them to have a good home and want to address the overstock issue fast just put up free ads for them on here and I'm sure you'll find good homes for them.
