Hmm, something tells me the killifish tank is in need of a pruning. The plants and fish love this tank. I have duckweed, giant duckweed, hydrilla, najas tenufolia, miniature bolbitis, standard bolbitis, narrow leaf java fern, miniature java fern, standard java fern, anubias nana and java moss. I only do water changes once every couple of weeks as the plants grow so quickly they take up most of the nutrients.
Also had to keep my clown killifish separate as my gardneri gold pair was trying to eat them through the bag.

One of the females
The only male
Chromaphyosemion poliaki female
Fundulopanchax gardneri 'gold' female. Her and her male are my favourites as they have so much character.
