options for a 45-gallon aquarium setup

I've got a 45-gallon tank collecting dust, and I'm thinking of setting it up in my bedroom - I've already got two larger tanks in the living room, each 150 gallons. I'm looking for some vibrant, energetic fish and was wondering if there are any African cichlids that would thrive in a 45-gallon setup. This tank might be temporary, as one of my bigger tanks is currently housing my baby koi until the pond is finished next spring. Any advice would be great, thanks.

To give you the best suggestions for your 45-gallon tank, could you tell us what your water hardness and pH levels are? Knowing this will really help narrow down some great options for you, especially when it comes to African cichlids.

Depending on your water parameters, I'd recommend considering the seveflake. They're small, peaceful schooling fish that can add a lot of movement and color to a 45-gallon tank.

I also think Rams and Malawi cichlids could be a good fit, depending on the water parameters though.

Not a good combo, Rams require soft water, while Malawi cichlids need hard water.

In my experience with similar setups, Jewel Cichlids and Kribensis have thrived with extensive plantings. Good water flow also makes Buffaloheads a delight to keep. I design my tanks to facilitate pair formation and reproduction, which adds an engaging dynamic to the display. The interactions between adults and fry are truly fascinating in these species.

My current tanks of similar size are home to breeding groups of Lyre-tailed Cichlids or Spotted Juli, both of which require plenty of larger rocks. These populations can quickly grow to 30 fish or more, demanding frequent feeding and close monitoring of filtration. The Lyre-tailed Cichlids are more visible from a distance.

I've also had the pleasure of keeping groups of Astatotilapia burtoni, which were incredibly entertaining with around 20 fish. The males would gather in one corner to build nests, and the females would visit them to spawn. This behavior seemed more natural than what's described in scientific literature, where males supposedly maintain larger territories and build nests farther apart.

I'm quite fond of xiphophorus maculatus, they're a great choice. However, be cautious as they can reproduce rapidly. A small group of 3-4 would work well, and pairing them with a school of 7-10 hemigrammus erythozonus could create an interesting dynamic.
