In the early planning stages at the moment but the end goal is to convert from my current community set up to Cichlid. I run a juwel trigon 190 and have a few questions I hope you can help me with. Firstly, what type of Cichlid set up could I have in a 190 litre tank? Seen a lot of stuff where people recommend over stocking these fish and seen some pretty cramped tanks!! Secondly, what filter should I run? A fluval 305 goes upto a 300 litre tank, would this be appropriate? Finally, what substrate would be best? I am currently testin at 7.4 ph so naturally quite high.
