Will update on the tank tomorrow, the rainbows have destroyed all the plants on the left side. I’m not sure on what fish to add to the tank, thinking of a group of different livebearers and a pair of smaller Cichlids to replace the rainbows, they are still in the tank and eating on all the leaf litter and plants. I like them but they’re slowly ruining the tank so they have to go. Any suggestions on what live beaters and small Cichlids I should add? I’ve decided on my solo big fish for the tank, either a cribroheros robertsoni or oscura heterospila. Does anyone know where to get these in the uk?
