all very good points. i asked because i often go to my fav. lake and stream near my house to catch swordtail, cons, and tilapias for my fish to eat. problem is, i just turned my old feeder quarantine tank into an exodon tank.
and quarantining fish also means you have to change their water, filters, feed them, and maintain them until they can be fed which is starting to become equally expensive. not to mention, if i start running out of fish, putting more into the tank means i have to wait even longer before they are food worthy.
but if i can feed them right off the bat if i froze them, that eliminates having to care for the feeders, feeding etc. and they can just be held in a stock in my fridge.
