Hi, I currently have an 8 gallon biocube which is heavily planted and my list of species are crystal red shrimp, amano shrimp, weitzmani tetras, boraras merah and scarlet badis. Tank has been set up for 3 weeks. Temperature is at 76-78 F and I have no ammonia, no nitrite and 10-15 ppm
nitrate. Problem is, I got 5 Weitzmani tetras 4 days back and they are always hiding at the back of the tank. I've read that the Weitzmanis and rasboras need a pH of 6 to thrive but the rasboras seem to be ok with 7. Is the pH too high for the Weitzmanis or would they show themselves soon? Thanks in advance.
