Appistogramma Cacatuoides

[lowthy76]

its 120 litres, and depending on what you read some even say having loads together as they shoal together in the wild.
i did have problems at forst but now there is a happy pecking order, and they each have territories at each end of the tank, and now that the female has turned yellow i think its only a good sign so fingers crossed

In a tank that size I would just have the V's but it may work if you have enough caves and sight line breaks. The females colour definitely indicates towards the positive!
