can i change from a cold water tank to a tropical tank i had 3 fancy goldfish in the tank but they died my water level are all up to date i do water changes every mayb 3 days 25% BUT NOW I WANT TO GO FOR TROPICAL FISH DO I HAVE TO CLEAN OUT THE HOLE TANK OR JUST CLEAN SOME OF THE WATER OUT thank you
You need to maintain higher temp for the tropical fish.
But before putting in fish be sure that the tank is cycled completely. For more about cycling read this
And carry on the partial water changes
I ONLY HAD 3 FANCY GOLDFISH IN THE TANK WILL I HAVE TO EMPTY ALL THE WATER OUT OR CAN I JUST DO WATER CHANGES AS ALL MY WATER LEVEL IN THE TANK ARE ALL GOOD PH AMMOINA ECT THANK YOU
All good means are ammonia and nitrite 0 and nitrate under 40? If so then start adding a very few fishes once a week. DO NOT add many fishes at a time
You may want to change 20 or 25 percent of the water as a precaution, but tropical fish will do well if the water parameters are satisfactory. There is no need to start over.
COOL THATS GREAT NEWS AS I DIDNT FANCY TAKING ALL THE WATER OUT THE TANK THANK YOU
I DONT NO WHATS GOING ON IN MY TANK,,YESTERDAY MY 3 FANCY GOLDFISH DIED I ONLY HAD THEM 2 DAYS THE AMMONIA AND THAT WAS FINE I TOOK THE FISH OUT THE TANK AND THISMORNING I TESTED THE WATER AGAIN AND THE AMMIONA WAS AT 0.50 IVE NOW HAD TO CLEAN BOUT 60 LITERS OF WATER OUT MY TANK IS 230 LITRES CLEAN ALL THE GRAVEL AS I THOUGHT MAYB THE DEAD FISH HAS CAUSED THE AMMONIA TO GO HIGH AS WHEN I TOOK THE FISH OUT THERE SKIN LOOKED AS IF IT WAS FALLEN OF THEM I DONT NO IF IM DOING SUMTHING WRONG JUST SEEMS EVERYTIME I PUT FISH IN TANK THEY DIE AFTER A DAY OR SO EVEN THOUGH MY API TEST KIT SAYS EVERYTHING IS FINE THANK YOU PLEASE HELP
Netting and moving a fish to a different aquarium is very stressful for them. In addition, their new home probably has different water parameters than their previous home. This is another shock to their immune system. The result is often fatal. Drip acclimation will significantly reduce moving stress::
Any decaying organic matter, including dead fish, will produce ammonia. If you do not put more fish in the aquarium and instead add a small pinch of staple food every other day, here's what you can expect while the nitrogen cycle is developing:
Converting a cycled cold water tank to to tropical tank in theory should be fine but since all your fish died there may be some disease in the tank. I would be cautious about adding fish to the water until you know what killed your goldfish.
What size tank is it and how many goldfish were in there? Did they look sick before they died? did they have any white spots or fin rot or were they gasping at the suface of the water?
Again. Did you cycle the tank before adding the fish? (it would have taken at least 3 weeks for the good bacteria to develop)
Did you condition the water? (adding Prime, stresscoat or some similar water conditioner to remove the ammonia)
Do you have a filter in the tank? Goldfish are notoriously dirty fish and produce LOTS of waste. you need to overfilter a goldfish tank -- and really any tank that has fish in it.
Also are you testing only for ammonia? (it has to be 0 for it to be okay -- any more and it may be tolerable for a short time but it is not okay) or are you also testing for nitrites and nitrates? Nitrites need to be 0 and nitrates less than 40.
Drip aclimation is the way to go about adding your fish when you do. add then slowly a few at a time.
woops I did not see that this was a three month old post. Shame on me...
Older postings can be very informative, so there is nothing wrong about continuing a discussion.
I know this is a late answer but I would recommend getting live bearing fish such as guppies, mollies, Platys, and swordtails. These fish are good breeders so you should expect to get some fry ever so often and plus they make good community fish and come in lots of colour
