I must say the breeding that has gone on is amazing. You tank set up has been ideal. I never fully realized the size of your tank till I did the liter to gallon conversion. The size you have is one I wish I had. Well, maybe one day. I plan to set up a 38L tank hopefully in the next couple of weeks. How many opae is in your 140L now?
Another question. How many did you originally start with? Did you buy yours through just one breeder? It seems you have different varieties or opae that may be from all 3 islands, Oahu, Big Island, & Maui?
