Gouramis are my favourite fish. I have a vision 180 litre tank. Wish I could figure out how to upload a photo from the iPad to show you all / I have 5 pepper corys, Pakistani loach, 2 ancistrus, 6 harlequins, 9 glowlight tetras, 2 pearl danios and two phantom type of tetras (rescue) my ph normally runs nearer the acidic range 6.5 ish although I do use a buffer as I use RO water, just need to get adjustments correct. I want a splash more colour in my tank ie cardinal tetras or neon tetras but am waiting for my PH to lower through water changes first. Currently at 7-7.4 ish. I don't want a predatory gourami so unfortunately appreciate the fact that the hardier three spot or pearl Gouramis are ut of the question. I have discounted also the dwarf due to the skin type diseases they get. I preferably wanted a hardier type but know they are all out, so which would you suggest? And just one male or a few females? I have lots of swimming space free, and the aquarium is very well planted, I would upload a photo but think too many pixels?? Ha ha, no computer whizz / advice very much appreciated and taken on board, thanks in anticipation!
