- Super-flat design. Fully submersible, modern design for energy efficient Aquarium and terrarium heating. Includes reversible holster/bracket, which allows heater to face inward or outward. See the product images to determine the best neo-therm size for your tank.
- Accurate, one-touch system. Simply set temperature between 66-96°f with one touch and the neo-therm electronic thermostat will maintain Tank temperature within +0.5°F. Led displays both set temp and actual temp, simultaneously.
- Ultimate safety and reliability. Integrated thermal protection circuitry prevents heater from overheating. If you forget to turn it off, the neo-therm will automatically shut it down.
- Virtually indestructible. Unlike cheap, glass heaters, the neo-therm is a resin/thermoplastic heater with a shatterproof outer-casing. Made in Poland and includes a 3-year warranty.
- Manufacturer You can trust. Most manufacturers rate their heaters on the ability to raise an aquarium 2-3°f above ambient temperatures. This is unreliable and misleading, as the average home fluctuates 2-3°f or more throughout the day. Cobalt rates The neo-therm on the ability to raise a tank 11°f above ambient temperatures, so you will never have to worry about overworking the neo-therm or it keeping up!

For those interested my light is an AI Prime LED set to the 14k spectrum.
What kind of filter do you have? You can put a sponge around it or change the filter, I have this one that helps distribute warmth throughout the tank. I think he's probably spending a lot of time next to the heater because as you stated it is on the cooler side, especially at night. Ideally you want a heater that maintains a stable temperature throughout the day. Maybe also consider getting a heater with more watts so the temperature is able to remain more stable? I use this one, it does a great job and is a little more expensive than other heaters but keeps the temperature stable throughout the day. However with your 29 gallon tank you may need a higher wattage.
Location? If it's in America, you can grab any good heater for this price.
Cobalt Neotherm $42
Aqueon Pro $25
Eheim $24
I wouldn't really recommend any heaters other than this trio besides maybe the Fluval E series, but they are too chunky for my liking.
You really do need a heater for a betta. They like their water between 78°F and 80°F, and water doesn’t warm up as readily as air.
I have a [Cobalt 50w heater](Cobalt Aquatics Neo-Therm Heater, 50 watt https://www.amazon.com/dp/B008AGWZCC/ref=cm_sw_r_cp_api_3pceAbCDMFY9M) and I love it. It’s a little more expensive than the other two heaters I’ve tried (Marina and Aqueon Pro), but it has a thermostat built in and the temperature is always accurate when I check my thermometer every day.
It's a bit unclear what your experience level is. You mention "upping my game" but then say it's a "starter" tank.
I have a 2.5 gallon Fluval Spec III which has been running for about a year so I can give you some insights.
A refractometer is an excellent tool to invest in and will help you make accurate measurements.
Any salt mix that advertises as being "reef" formulated is probably fine, I seriously doubt there are big differences between brands.
Aim to do a 30-50% water change every week. Even if you slack off you will still generally end up doing it every 2 weeks which is a good pace. Water changes are essential to replenish trace elements and remove wastes.
For smaller tanks, Cobalt Neo-Therm Heaters are a good choice and have a slim profile. 50 watts is plenty for a 5.5 gallon tank (I have a 25 watt).
Get a two glass thermometers, one for the "display" of the tank and one for the rear chamber. Check them daily.
Get a suite of SALTWATER SPECIFIC test kits that cover pH, Nitrates, Nitrites, Ammonia, Calcium, and Carbonate Hardness (alkalinity). Test strips are nice to have for spot checks but are not to be relied upon. The only parameters I actually check regularly are pH, Calcium, and Alkalinity. Once the tank is stable, other parameters are unlikely to fluctuate much between water changes.
Invest in a good light! Seriously, it's one of the most important pieces of equipment so don't skimp out. You could get away with something like this if your corals aren't picky (I did for months with this light and it actually grew SPS alright) or a dodgy Chinese LED fixture from eBay, but I recommend something like the AI Prime HD (which I just upgraded to). It has built-in wifi control so you can set things like color temperature, auto timing, and weather patterns.
For a small tank, an auto top off (ATO) is essential. I have a Smart ATO Micro and I love it, works perfectly. Without an ATO your water will evaporate, your salinity will fluctuate, you can't risk leaving it alone for more than a day, and if you neglect it your pumps might even run dry and destroy themselves. Trust me, this is $124 well spent.
Upgrade your return pump from stock. I put an AquaTop SWP360 in the back of my Spec III and it works really well, good flow and just the right size. In a 5.5 gallon tank you might get away without an additional powerhead for flow, but I'd recommend a small (small) powerhead for good measure. (Pro tip: repurpose the stock return pump for that!)
What else...
Get GFCI power strips so that you don't electrocute yourself.
If you're getting a Fluval Spec III or V, consider investing in this excellent media basket.
Well that's some good advice to start from... let me know if you have questions.

Thanks! The heater is: https://www.amazon.com/gp/product/B008AGWZCC/
It fits pretty snug back there, so that's a bit concerning, but it's working out fine so far.
Way to go with the upgrade! I'd go with the Aquaclear 20 and the EHEIM Jager heater. The heater my be a slight bit more than others but it's not going to fall apart in a year and need to be replaced. Cobalt Neo-Therm is by far my favorite heater is more expensive but so easy to set an looks much better in the tank.
Edit: Also wanted to add that you should save any filter media from your 2.5 tank to add to the new filter. This will help you get you new tank cycled a bit faster.
I use this one.
Only issue I would see with a higher watt heater would be the size. It might be physically too large for your tank.
I use these in most of my tanks ($32 or pick one up at PetCo by pricematching to their online price):

And this $42 in my Caridina tank (used one is $27 if you want to save some more):

The filter is the one that comes with the edge, basically an aqua clear with a sponge prefilter. The heater is on the right—is that what you’re looking at?
