Harlequin rasboras have been incredibly popular in the aquarium hobby since the early 1900, and while they did fall out of favour for a while they have made quite the comeback thanks to people looking for small fish for small tanks in put in their small houses!
Harlequin rasboras are supremely gentle fish that are perfect for a community setup or if you are looking for fish that is nice to look at, but wont steal the show from your aquascape.
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
AP-3 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.
