Exclamation point rasbora also known as the sparrow or least rasbora are one of the smallest fish available in the fish keeping hobby. They are perfectly suitable for smaller aquariums, although not nano size, but do bare in mind they are certainly not the easiest of fish to keep long term. They do have quite particular water requirements and are not suitable for keeping with the vast majority of other fishy tankmates.

My favourite fishy stuff! (yes these are affiliate links :) )

Lights
Nicrew Classic LED https://amzn.to/3fG3Uv6 Traditional led light that's got a nice high output in a white/cool colour range. Makes plants look extra green.
Nicrew SKY https://amzn.to/3Ktn45U really nice light for natural looking tanks, also the one I use for filming.

Filters
Pat Mini https://amzn.to/3fE1u0k popular for a reason, just a superb little filter thats great for shrimp tanks and fish alike.
ASAP https://amzn.to/3nBuytp the old favourite and the one i return to most frequently.

Air Pump
AP3 Kit : https://amzn.to/34UMA3q Great little air pump, not a silent runner, but has been very reliable for me.

Tanks
Scaper 45 https://amzn.to/3KBxG2H a lovely high quality tank that comes with a super strong light, and a decent enough hang on back filter perfect for newbies and scapers alike.

My filming stuff
Camera Cannon 200D https://amzn.to/354OLlc nice camera, easy to use.
BigTripod Manfrotto befree https://amzn.to/3GLXDdj pricey but super sturdy and can take being knocked over a lot by clumsy operators.
Lil' tripod https://amzn.to/355WmQs can't pronounce the name but it's been a good tripod for filming things on tables or when I have tanks on the floor.
