So if anyone here has seen my earlier threads, you'd know i had considered putting one in a 10g. I know now that that is way too small...my 10g is now full with a betta and shrimp, 30 gallon is stocked with a pair of apistos and some loaches. However, I might have enough room in my 20. As far as the water conditions are in the 20, It has a ph of 7.3, and and pretty hard water. I know. Gbr have to have soft water (I think) and prefer a lower ph. I have almond leaves and peat moss though so that shouldn't be a problem when the time comes. I keep the temp around 80-82 farenheight. The tank has a few anubias planted in the substrate along with a couple crypts and 3 marimo moss balls. Also has driftwood and a plastic tiki hiding place, which I'm probably going to remove....I have a hob filter and a airstone which I kept in after treating for ich, also to compensate for the higher temperature. As for the stocking I have 6 cardinal tetras and 6 sterbai corydoras. Would a single German blue ram be ok with the corys? I know they dwell towards the bottom...if I left out anything important please let me know.
