Yearly update.
Both jaus now look to be around 40". In the last 6-8 months they have been refusing thawed fish but take pellets eagerly. It worries / worried me because this is what some others have done before eventually perishing after some time, many months or a few years, e.g., TSN, TSNxRTC, and TSNxLei. Good thing I have now switched to mostly NLS.
Or maybe because they are so big now, they don't want high protein anymore.
Another change I noted is that they fight not by season anymore but more or less regularly regardless of the time of year, which is why you will see split fins in the video below, especially on the beta one, Zazula, on the bottom in the thumbnail.
