If you wanted to keep a mandarin and feed it pods
you would most likely need at least one bottle or more per week. :-(
How long has your tank been up? Do you have a fuge?
I have an ORA mandarin in a 29g cube BUT he was supposed to be eating pellets and I had a fuge. I also had tons and tons of pods
already in my tank which had been set up for at least 6 months.
To be honest, I don't know if I would buy one again, it;s been ALOT of work getting her to eat frozen food and she probably would have starved if i hadn't had an immense amount of pods
