Rathbuns tetra are a delightful species that has far too many names - green fire tetra, and red flank blood fin tetra to name just two more. For the most part they are easy to keep and have very few specific needs, just be a little careful about their tank mates as they can be fin-nippers
My favourite fishy stuff! (yes these are affiliate links :) )
Lights
Nicrew Classic LED - 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 - amzn.to/3Ktn45U - really nice light for natural looking tanks, also the one I use for filming.
Filters
Pat Mini - amzn.to/3fE1u0k - popular for a reason, just a superb little filter thats great for shrimp tanks and fish alike.
ASAP - amzn.to/3nBuytp - the old favourite and the one i return to most frequently.
Air Pump
AP-3 Kit : amzn.to/34UMA3q - Great little air pump, not a silent runner, but has been very reliable for me.
Tanks
Scaper 45 - 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 - amzn.to/354OLlc - nice camera, easy to use.
BigTripod - Manfrotto befree - amzn.to/3GLXDdj - pricey but super sturdy and can take being knocked over a lot by clumsy operators.
Lil' tripod - 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.
