moved house now got a much bigger 250l tank set up and got all my other bigger fish in there. This meant I could keep the Marmaratus in the 150l tank on his own. So he's got his own tank now. Running a big external and internal filter as well as a nice big air rock and 16 tropical plants. So iv followed your guys advice he has real plants plenty of air and nice clean water
As for feeding it's been hard and taken a lot of patience but I got his from worms to white bait and now he's consistently eating massivore pellets which I'm very happy about. I'm currently on the hunt for another Marmaratus to put in with him but it's going to be hard to find someone selling one.
Thanks for all the advice anyway guys you've been brilliant. If anyone comes across one for sale please let me know
