Advanced tanks aren't being recognized.

9X9 Water source blocks with corners cut off as shown in Wiki, walled in with glass (overall 11x11 with corners cutt of). At 3 blocks tall fish report its too small, at 4 blocks tall they cease giving me this error and show a red health bar, and green health count but the feeder is still not running.

Restonant Rise pack 2.7.1.1
Tested in simple flat single player world with a glass and grass block floor.

The concept of those tanks is no more. It only counts the water around it now.

That's good info, wish it was in the appropriate book... :)

BUT... the end line of fish starting with nightfish, tested with both enderfish and dragon fish once you get them to stop bitching about tank size still do not breed. Their health bars are red with no complaints, the feeder reports they have a bitch to give, but the only thing that appears is their health count in green as reported in earlier note. Is there something else I'm missing?

You have to do the breeding in the end.
