I was going to get either 2 german blue rams or 2 bolivian rams for my 36 gallon long tank but was just wondering, could I get 1 german blue ram and 1 golden ram instead? Would they fight if I still made sure I got 1 male and 1 female? Would they breed? If I could can someone tell me how to sex the golden rams please.
Also, can I add 50 litres of R0 water to a 138 litre tank in one water change or will it drop my ph too suddenly (my tap water+tank ph was 8.2 until I added 25 litres of R0 water last week, its now about 8. The RO water PH is about 6.8) should I do 25 litres today and another 25 litres in a week or 2 or can I add the remaining 50 litres today? Thanks, laura
