Its 260 litres approx 55 UK gallons.
No the gourami is actually quite gentle and doesnt really bother anyone exept the outlet pipe for the external filter which he enjoy wrapping around until the water fires him to the other side of the tank! He only seems to do this at night, had me kind of worried at first but I honestly believe he is just amusing himself
Stocking list is as follows.
5 x panda cories
2 x skunk cories
1 x bronze cory
19 x Glowlight Tetra
4 x swordtails (all male born in tank 2 years ago)
3 x guppies 2 female, 1 male again all bred in tank.
54 x glass cat fish
2 x breeding Bristle nose plecs, several batches of babies (not sure how many will survive but I have spotted 1 over 1inch now.
1 x kribensis pair Only Male left, RIP Female
1 x pink gourami RIP Buddy
1 x GB Ram (Male) lost the female
2 x botia loach
3 x False SAE
8 x Japonica shrimp, maybe more!
I think the tank is a little overstocked possibly but my water stats are alway excellent (0 Ammonia, 0 Nitrite, 20 nitrate)and I have a regular weekly maintenance schedule. The tank is also very over filtered with an internal 1000LPH pump and a Fluval 305 external pump.
I will post some more photos of the whole tank when I get a chance.
Please feel free to advise on the tank and its inhabitants, I know the kribs may become a nuisance and may even eat my shrimp but they have been housed in here through neccessity due to other tank issues, currently they a quite placid though so fingers crossed.
