Not sure I'm in the UK but it's around 290L. Not sure what a severum is but the rest is right plus 3 catfish 2 ghostk knife around 6 SD 2 tire track eels 2 placos 4 jewels 2 are young. I think that's it . Yea that's a lot looking at it like this lol .I think I'm overcrowded lol .
Thanks for the advice. And I'm sure you are going to say pretty much every fish I have gets that size or bigger . So how do I choose ? I like them all this will be hard lol.
Until you have time to get the stock way lower I would do a lot of water changes. Also look into the solution bottle test kits. More accurate results than strips. GL
