I keep them in a standard 10g (horizontal-oriented). The imitators have been in this type of setup for about 10 months now...the male has called, the females wrestled each other sometimes, and a few eggs were laid. The plants are the same for the 'Blue Jeans' tank; moss from Peaceofthetropics, Neo. compacta frm TandC, and Syngonium sp. from BlackJungle.
:Well i see that you said that all your tanks are 10 gallons but are your imitators in a standard 10 gallon or 10 gallon vert? Also i would like to find more about the imitator tank setup and what plants your using, etc. Also those are great pics you did. Thanks for Sharing.
