Found one that eats, great, that’s a score. Feed lotsa sponge and fresh unfrozen foods and it will live for years.
Have seen again and again people who get them to eat, watch them get fat, then watch them die.
For people considering an idol, or trying to get one to eat, sounds weird but....
New life spectrum is in most cases the best way to get them to start eating. But even if they’re gaining weight will not sustain them for long. This has been my experience
