What do you have in the tank?
Severum, jack dempsey, parrot cichlid (2), tinfoil barb, 3 corys, 2 3 spot gouramis, 1 paradise fish. Piece of wood I found in a lake, I boiled it before hand.
How long has it been in there? Since I set up the tank, a few months.
What kind of substrate? Sand. I clean this almost daily.
Decor? See above.
How often do you do water changes, how much do you change out and what system do you use to do water changes?
I do water changes every 2-3 days, I change out 25%, I just syphon it and add treated tap water.
How often, how much and what are you feeding?
Usually I feed a good chunk of frozen mysis/brine shrimp in the morning (about 2-3 packets worth probly, I buy the kind that comes in a bag). Then at night I feed the same amount of bloodworms. In the afternoon sometimes they trick me into giving them a snack. I know they say to keep your fish "hungry" but I know I wouldn't like to be hungry all the time, when they are fully fed they seem to play more and show more of their personalities, they also aren't leaving any food fall to the bottom and anything that does the corys eat right away, so there isn't any rotting food or anything. Although, yesterday I ran out of food, so I fed them some frozen talipia (the kind for humans) and some avocado, could that have done it? Because the smell just started today. Like I said it's not that bad, you pretty much have to actually bend down and smell the water, it doesn't stink the whole room up.
Oh yeah, I have some anacharis plants and a onion bulb and some other plant, the onion bulb roots were rotting the other day, they seem ok now, on that note. Should I get new plants for the sand? (just changed to sand a few weeks ago, had the plants before I had the sand) Or is it possible to save them maybe, they aren't dying they are just not growing well anymore, does the sand need fertilizer? Could you maybe suggest some plants that would do well in sand substrate? I would like as many plants as possible without c02 and low lighting.
