yes i agree, it is currently over stocked, but some fish are moving, as i said in the 1st post. The bnoses and dora are moving soon, the loach will be moved when they get too big for the tank (and not to small for the Oscars mouth), and the khuli's are going to be moved when a friend has the capacity for them.
I didn't buy the khuli's and change my mind, before you ask...they were given free - as were the bnose cats - with 2 tinfoil barbs,2 silver dollars, and a chalceus. The latter went into my 6ft tank straight away due to size, but the khulis and bnose were a little small to share with a 10" Oscar.
The 'rule of thumb' of 1" per gallon is not exactly precise, as im sure you'll agree.. 1" of pleco, or Oscar is a LOT more fish (and thus waste) than 1" of TB. This combination of low waste fish, and tap water with 0ppm of nitrate makes life pleasnt in the tank. With weekly changes of 20-25%, the nitrate ppm is rarely above 20, and the most it has even been was 40, and that was in the 1st month of setting the tank up (march 2005).
I did do some planning on this, and did calculations on gravel depth/grain size, and filter size/flow rate to maximise the stocking capacity by using PFK's calculators. the theoretical maximum i can achieve is 98" of fish, if built up gradually (i think 14 month is gradual enough
)
At CURRENT sizes, i am marginally over this, due to the bulk of the dora, and the poop of the BN's. I think the Dora is Oscar proof by now, so chances are s/he will be moving at the weekend. Hope the RTBS is as good as the Dora for eating the mountain of eggs that appear every waterchange!
