If he doesn't perk up, ping Tynk or IDzine and see whether they have any
ideas. Both are betta breeders and experts.

I don't breed bettas I just keep them... love too, but I don't ...
That's all Tynk.

Actually, I'm not an expert either. Sounds nice though. I think of
experts as those crazy guys at the aquarium clubs who speak of aquarium
fish only in their Latin names and use lots of acronyms. You know, the
one's who spend all their wife's hard earned money for one more trip to
Malaysia, China, South America... etc to wade through leech infested
swamps and photograph long lost wild species. I watch them in awe.
