It is Mayfly Nymph due to the three long cerci(tails).
Most species feed on algae or diatoms, but there are a few predatory species.
For most the people who are living in flat or condominium in Singapore, the most likely unwelcome visitor in your tank will be the Mayfly nymph. Damselfly nymph is rare and getting dragonfly nymph is nearly impossible.
The Mayfly manage to find your tank by the lighting you are using, especially in the evening.

I did that when I was a child.
I tied a string to the tail and follow it.
Most ended up with a broken tail.
Silly things for me to do as they do help to eat mosquitoes and other pest.
They are welcome to fly around but not welcome to have their alien looking nymph in my tank.

Is there no way to make "traps" to catch them? Instead of turning the tank upside down to net them out?
They feed on water plants and algae.
If you do not believe me, you can throw in a cull shrimp.
It is good to give some moss for them to feed on.
As adult, they only have 1 day of life span, so it will be cruel to cut their wing.
They going to have sex for the first time and then died, many never even make to that stage and were eaten by bird and other bigger insects.
I was thinking of that too....but seems like bro hyun007 knows quite alot about those buggy stuff...and did indicate that Mayfly Nymph feeds on Algea and Plants and will not feed on shrimps.
If there were such traps....I won't be having a hard time whenever i see them visiting my tanks.
HoSay...bro...at least i have an answer to it...Even when i grows???It will not attack shrimps at all???
Bro...You seems to know alot of stuff about buggy...
Thanks god to have a buggy person in forum....
Cause my previous visitor also from the same family...S*cks!!! makes me turn the tank upside down....
Can you enlighten us which kinda nymph will actually attack and feed on shrimps???
Mayfly Larvae Diet
By Sandra Parker, eHow Contributor
Mayflies come in many different varieties, however, the larva or juvenile stage of the insect behaves very similarly. The larvae eat algae throughout their development, which can last anywhere from two months to two years.
Habits
Mayfly larvae can be found in wetlands throughout the year, despite the implication of their name. Larvae begin eating from the moment they hatch with the sole purpose of growing and developing until they emerge as adults.
Omnivorous
Mayfly larvae are omnivorous, eating planktonic, or free-floating, algae throughout their lifetimes. occasionally picking up microscopic animals as well. Very few mayfly species are strictly carnivorous or herbivorous.
Scavegers
Mayfly larvae can also find nutrition in the excrement of other animals such as fish, turtles and other aquatic species. This helps keep the water quality in tiptop condition.
Considerations
Mayfly larvae eat voraciously as they require a large amount of energy in order to perform the complex transformations their bodies undergo as they approach adulthood and prepare for reproduction themselves.
Adults
Adult Mayflies do not eat at all after emerging from the larval stage.

Bro this the 2nd time you got them?? They dragonfly sure love flyng into your house........... Do fast hand and fast leg catch they can stay up to 3 yrs in that form feast on your shrimp or shrimplets. The longest piece i caught lasted 8 mths i think it ran out of food to eat.
I remember feeding them guppies when I was young.
I had the green color one as well, but they are vicious predators.
