Greg As for Colony experiences..... I presently have my Sp Maulbruter in a 55 gallon tank, lots of hiding places among the plants driftwood and flower pots.... I have 2 pairs in this tank, both spawn and i have lots of little guys of different sizes swimming around with Both Pairs.... The breeding areas are on either end of the tank with lots of stuff in between so neither pair can see the other with all the stuff in the middle.... fry swim from one end to the other without any harassment from either pair OR the larger group of Acaricthys Heckelii i have growing out in this tank also..... the Heckelii are about 4"+ and dont go after the apisto fry... which is cool John ----------------------------------------------------------------------- -- This is the apistogramma mailing list, apisto@listbox.com.
