I used to feed twice a day with fluval bug bites (two medium-ish sized pinches), but then I realized they were getting a little 'chonky.' I switched to feeding once a day (one medium pinch of fluval bug bites). Pretty recently, I started to feed frozen live food, occasionally, in place of the 'bites'. I've only fed frozen live food twice. The tank has been going for roughly 5 months now and this specific rummy is acting normally. I know identifying genders of rummies is difficult, but this one doesn't seem sickly. From the single video on youtube of breeding rummies, the guy said he had success with getting them into the 'breeding mood' by feeding them frozen live. Any thoughts/experiences?
