Hello.
Got two queries here.
1) My two RES of sizes 4" and 3.6" respectively produce so much waste that I have to clean the tank every 2nd or 3rd day even though I do have a top filter and a small waterfall filter in place. So, is there any alternate way of keeping the water clean for a longer period say a week. Not that I am fed up of cleaning the water for the RES, I do regular WC for my discus tanks, just want to know of alternatives if any.
2) Posting a picture of my two RES, actually the tail pics, would request the experts to i.d if its a M/F or M/M. I do understand they are still very young. Took the nail pics but not much of a difference there.
Thanks
Simanta.
