Black Molly

[veerushark]

I have a tank of 4to5 gallons capacity i had kept 2gold,2cat shark,2zebra,2platy,1guppy and one male black molly and white female molly.
My black molly after 1 day of changing the water it starts gasping at the top of aquarium but white female will be normal roaming freely.
I dont use any filteration system nor any bubble creator and i cant afford it.when i change both to another small tank of less than a gallon tank it will be sitting at bottom looks as if ill. From one week i m using methylene blue treat meant to the tank now all are healthy but this is ill i think so no white spots on it
So please tell me suggestion for this.

Just to clarify - did you mean 45 gallons?

And by Gold, did you mean goldfish?

 

[dafrnhm]

he might mean gold gourami?

I actually made a post the other day about this, I had a fish that would mouth at the top of the water constantly, I then added more airflow to my tank and surface agitation he is fine now.

Your tank is far too small for any of those fish. with no filtration you will have constant water problems with ammonia and nitrite buildup and no oxygen circulation. This is why your fish are gasping.

If you can't afford/won't buy a larger tank with a filter, please don't keep these fish.

Rehome all your fish, and get a couple African Dwarf Frogs. They don't need filtration, and will be fine in that size tank. Add some anacharis plants to the tank, and some other type of cover decoration for the frogs.


That tank is small for even one of those species. They require more swimming room than that.


Another option would be to get a betta. They also do well in that size tank, but require a little filtration.
