Gary said: 3 days ago, I added an iron supplement for my plants. The taenia have gone from being a curious but drab fish to absolute striking coloration. 3 females spawned within hours of each other yesterday, as did the cacatuoides. All of these fish, bar one pair of taenia, hadn't spawned in months. local plant guy once told me about Anomolochromis thomasi always spawning after he'd added trace elements (his own secret formula. as anyone out there seen similar things? Gary--I hadn't had that happen to me, but it reminds me of a scene from the move "When Harry Met Sally" when Sally faked an orgasm and embarassed Harry in a restaurant--the lady at the table told the waiter "I'll have whatever she's having". So can you go into detail about what it is that your Nanacara Taenia and cacatoides were having so I can try it out? Thanks. ______________________________________________________
