Hi Jerry, >What kind of live food are they guarding? Some of my females guard daphnia and grindal worms. When I feed my new apistos with larger daphnia like D. magna for the first time, both male and female start cleaning daphnia in their mouth just like they do babies. It's really funny to watch. But once a female gets into this mode of guarding food and chasing her partner away, it is not easy to coax her out of it. As for my aggie, the lyretail male is her second victim. After the painful initiation of tail biting I can't blame my male aggie for avoiding his feisty partner. I just replaced 25% of their tank water with DI water tonight. We'll see if this makes any difference. Tomoko ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
