Do i need a heater so my swordtail can survive?

Question

My swordtail stays at the top of the tank and stays there most of the time it stays there and doesnt swim any where else.... what should i do.
Why would he stay up there all the time?

I have 3 other fish along in the tank which are:
Angel fish
Dragon fish
and a Black Moor...

The black moor looks like its sort of twitching is that a sign that i should take him out?

Answer 1

Yes you need a heater unless you live in a warm climate where the ambient water temp is around 80f, The black-moor requires water temp of around the 60/65 area and is really misplaced, the angel comes from the amazon area and above 80f would be the norm.
Angel fish are not aggressive, they are however a cichlid and will devour any fry in the tank.
I've no idea what a Dragon fish is, you could be referring to an Arowana, or maybe the eel/catfish type, in either case it don't really matter what temp you have because that's the only fish that will be in the tank in a very short period of time, both those are extremely quick growing and are likely to devour anything they can get in there mouth, both will become to big for you tank unless you have 180/210 gallons, or its something that has a different generic name.

The swordfish is a mid to top living fish the fact that the top of the fish is flat and the mouth upturned means he will more than likely spend more time in that area as thats where he would normally feed. However, it could be that he's a little worried like me about whatever a Dragon fish is.

Swordtails are tropical fish and need to be in warmer water. Also aren't angelfish aggressive? If you have the fish with aggressive fish it may be scared to swim around. This can stress out the swordtail and cause it's immune system to drop and it can become ill.

definite except you reside in a neighborhood the place room temp will continually be 20 -24 Celsius. in case you reside someplace the place it gets chilly , you will actual want a heater for the wintry climate, pondering those are all tropical fish that like temperatures between seventy 5 and 80 two Farenheit

Answer 4

the black moor may be carrying a deseise and could kill the other fish so take him out and thw swordtail depends on what kind u need a heater or not

Answer 5

A swordfish is a tropical species of fish. Its water temperature requirements is about 75 degrees. So yes you do need a heater. Why do you have it with a species of gold fish? Those are cold water fish and wont be comfortable with higher water temperatures.

Answer 6

your black moor is a goldfish,
your angelfish and your swordtail are warmwater fish and need to be around 76-82
and your goldfish needs to be around roomtemperature

Yes you do need a heater and need to take out your goldfish as well

Good luck
