Looking to the future after our 'accidental tank acquisition' as per my previous posts, I have been enjoying making a stocking plan, which I want to share for your honest opinions and advice.
Few background bits - we have a Juwel 350 (4ft) cold water tank with All Pond Solutions 1400 EF+ canister filter (with recently added Seachem Matrix in addition to boil balls, activated carbon, ceramic noodles and sponges that were previously cycled).
The tank is currently housing 3 juvenile Weather Loaches and 6 juvenile Gold White Cloud Mountain Minnows, sand substrate, bog wood, pebbles, slate rock caves and numerous live plants. Due to the tank move, from a 3ft, three days ago we are sticking with the current stocking (until we have reliable nitrate, ph and hardness readings for a good while).
Water testing is coming back good, 0 ammonia, 0 nitrites, nitrates changing due to new RO water but lowering and no mini cycling so far (can't remember the dang results but I have them in my notebook which I have left at work!). 10% water changes daily and we are gradually lowering the hardness after installing the under sink RO unit, to suit the loaches. Seachem Prime (and Stability as a precautionary measure) being used as per instructions.
We do have plans to get a 5ft tank next year but need to do a few renovations to the house before we can fit it where we want it.
So, based on the above, I have followed the links provided in the other thread and have come up with the following stock list. It includes current fish, so will be a total stock, not additional, so to speak:
Your stock list sounds fine except for the cories which need a group of six or more rather than only three. You might find it better to have two larger groups of shoaling fish rather tha three smaller ones - depends on what you find pleasing to the eye, but personally I think one or two bigger groups are more interesting to observe.
