Heater sorted, temp normalised around 26c atm... Weekly water change done, and my lad got 6 penguin tetra as he loved the way they school together at the shop.
Think we're done stocking the tank now as I'm concerned about the bio load, though one of the shrimp seems to have upped and vanished like a fart in the wind. No sign of it. Not even in the filter.
Next piece of equipment is a better gravel cleaner the one I got from pets at home is okay for draining water but doesn't have enough suck to pull any gunk off the bottom.
Definitely realising the limitations of the fluval edge the narrow opening at the top, proprietary design of the filter which seems lack luster and difficulty to fiddle around inside really making me want to migrate to a better tank design.
I suspect you really have bought six of the "False Penguin Tetras." They get far too big and active for a Fluval Edge, I wouldn't keep them in anything smaller than a 90x30x30cm tank.

As a social species, it will do so much better and look better in a bigger group of 10+, in a mature tank setup of more suitable length.
In my opinion, Fluval Edges should not be sold as fish tanks, they are overpriced transparent sardine cans for people who like the novelty of keeping fish but often don't think of the fishes' needs. Not to mention, such tiny volumes of water are easily turned into toxic soup, especially in the hands of fishkeeping rookies who often get too many fish too soon and consequently completely overwhelming the vital ammonia and nitrite bacterial colonies.
Fish shop sales people will often tell you what you want to hear for a sale of fish, get into the habit of doing fish requirement research and then buy the fish. It will save you money and heartache, while possibly saving the lives of fish.
When I started keeping freshwater fish in 2010, like many I was paranoid about having a heater active in every tank all year round, set somewhere in the 24C ballpark. A year or so later, I read
http://www.seriouslyfish.com/whaddaya-mean-too-hot/ . I then removed heaters from all my indoor tanks and then only activated the heater in my garage Rio400 from around November to April... My five active indoor tanks contain a mix of low-end and mid tropical temperature fish, including species such as Congo Tetras and Dwarf Chain Loaches. The ambient room temp means these tanks' temps change through the seasons, typically ~21C in the winter and u to ~29C in heatwaves like last summer. The garage tank is a colony of sub tropical Mexican livebearers (Limones Goodeids), the heater is turned on down there during the winter to keep the temp above 18C.
. In the end, I upgraded my 70L tank to a 200L and replaced my edge with the 70L. Much easier to maintain now.
