I have, living in my 4 foot tank (264lt), 2 gold Severum, 8 juvenile Keyholes, 12 tiger Barbs, 1 Bolivian Ram(was 2 till recently) and 1 large Angel left over from a previous tank manifestation. I'm not planning on keeping all the Keyholes, am sort of waiting till they're old enough to keep a good pair and have homes for the rest sorted. Clearly the tank has evolved into a SA tank of sorts so what next? And plants, what sort of plants should I be looking for? Cheers.
