Stocking A Jewel 260 Vision

So we know the tank in question, it's a bow fronted tank 121 cm wide, 46 cm deep at the deepest point, and 64 cm tall (though that includes the air gap above the water).

One comment is that your shoal numbers are too small.


It is just big enough for Lake Kubutu rainbows which need 120 x 30 x 30 cm minimum. These fish need a basic pH (ie above 7) and hardness 10 to 20 deg (178 - 357 ppm. It is a skittish species which should be kept as a group of at least 6 to 8. You will probably find that just 3 will hide a lot.

Denison barbs, aka red lined torpedo barbs, latin name now Sahyadria denisonii - the tank is again the minimum size needed. Can cope with pH 6.5 to 7.8 and hardness 90 - 447 ppm (5 to 25 deg). This is another shoaling species which needs at least 6 to 8 with more being better.

Pictus - yet again the tank is the minimum size. Needs pH below 7 (so not really compatible with the rainbows) and hardness 1 to 15 deg / 18 to 267 ppm. Can be kept alone but a group of at least 6 would be better.

Congo tetra - yet another fish that needs at least 120 x 30 x 30, so OK for your tank. pH up to 7.5, and hardness up to 18 deg / 320 ppm. Needs a bigger shoal than 5.


Golden nugget - again the tank is just the minimum size. Needs a warmer temp than most fish at 27 to 32 deg C. This makes it not really compatible with the others.




I would lose one shoal and increase the others to their minimum numbers. And is there another plec that you like that is OK at 'normal' aquarium temps?


What is your water hardness and pH? That could help you decide which species to lose - if it's soft water, lose the rainbows; if hard, they should all be OK
