Wassup mfk, just picked up a 300 gal hahah it so big and I donno what to put in there... I really like large fish/ predators, what would you throw in there???
Lone predator. Worth trying a big lone predator for a while, once your stocked with a community it's alot harder to sell em all and try a predator.
Fish I personally would like to try alone in a 300 are;
Cuban gar
Fahaka
Black wolf
Manueli pirahna
Artc or wyckii alone (kept a wyckii to 2ft before but it was beating everyone up.)
Umbee male.
Something special about 1 fish in a tank, shows their true personality.
SA river community with ornatum, festae, atromaculatus, bunch of pikes, some silver dollars, a flagtail. Aquascaped with a bunch of plants and wood. Would be great in my opinion.
Or a Central American cichlid community tank, with 300g you could have all the parachromis species (accept the Dovii) couple of the anphipolous and some Texans . Would look great and very colourful width big aggressive fish... would need a very well thought out aquascape though!
