wow your mom must be rich you are going to have to get a lot of money off her soon 3000 euros should do it for the tank size you will need 4000 liters will do it
and that paroon shark will need an even bigger tank because of their activity levels and size they can get as big as a redtail and love eating fish aswell ! i know you love your fish but you will be better off with fish that don't grow as big in the long term believe me i know having kept fish that would outgrow my tank in the past,even now my rck could get too big but they don't always get bigger than 18"-24" so if it does i will have to then build a bigger tank in my shed ! i don't think your mum will like the thought of spending thousands of euros 'just' on a tank though, i hope she does though,good luck for the future
Yesterday evening RTC ate 1 shrimp and tried some ropefish noodles for desert.
The rope was to big for him to handle and he spit it out. The Rope is fine now.
