I keep a ten with one male betta and an assortment of small tetras (neon, cardinal, glow light, black neon, "18k" albino black, albino neon, and now green fire tetras) I consider each tetra a half inch of fish and have a baffled Emperor 280 on the end of the tank, so whichever male goes in has lots of company to watch and an already well established tank.
In order to acclimate new males to the living arrangements I like to "guess" when the current king-of-the-tank will go and get another male to put near the ten so they can learn how to behave. It works great, betta are very visual. Downside is I've never had a reliable good tank before. Always had to add cooling or heating, modify filters or add biological filtration but not anymore.
Found this little gem. It is a two gallon hexagon tank, it comes with base, tank, lid, power filter, power filter cartridge, moon/off/day light, removeable light shield, lid and power supply.
For me the most important aspect is the Power 5 filter. An odd filter in that it uses an enclosed double-sided cartridge with carbon inside that receives the water in from the bottom. There is no bypass at all so the filter can actually be placed LOW in the tank to slow the water circulation, we're talking almost onto the rocks at the bottom. The filter intakes water from the front AND the bottom so your little one doesn't have to worry much about becoming a pre-filter. It moves enough to circulate the tank even placed all the way down without rocks. The replacement cartridges are only available at petco but I don't see them running out of supply. A nice side effect of submerged power filter in this tank is it heats the tank! I've got it setting on a desk in air conditioned airflow and the tank is staying 78 to 80 degrees all day.
The tank body is a standard acrylic with a half inch tall quarter inch deep offset in the bottom to fit the stand ring. It tapers very gently wider going up, probably only to introduce triangular cross section for structure.
The base has four
notches in it even though the whole thing is powered by one supply line, this lets you route the power line AND your optional hydor mini (won't need it, see filter) line under the tank and back out to stabilize the cords or if you put it over a access hole in a desk it'd let mouse, keyboard, tank power and speaker wire come up through!
The lid has a lipped socket for the light, a small feeding door and a notch to one side on the back for the filter's hanging bracket and any wires or hoses you want going into the tank. The gap is small, can't even fit an eye dropper through it. It forces you to place the filter against one of the angles of the tank making the water flow circulate around as well as pillow over and over.
The light is a disk with the removeable "lens" screwed onto it that covers the bottom and sides so you can remove it and clean it with vineagar without risking the electronics. The light can be lifted out for reaching small hands, net, dropper, grabbers and whatnot into the tank. It has a BLUE "moon" setting that's actually kinda bright and the daylight setting uses lots of small bulbs and is bright enough for most aquarium plants.
The power supply has a six foot-ish cord and splits at the end for the light and filter connections. It looks like they used a camera style connector on the light just for convenience as the supply is standard 12v two wire. Just about any electronics repair place could put an adapter into the line so replacement 12v supplies can be used.
Lots of tidbits and details, yes.
Fluffy is a walmart crowntail, he's got a white head and goes from two-tone blue out through red and purple. With the filter hung just a half inch below the surface AND an air stone beside it, the circulation in the tank doesn't even phase him. He's constantly moving around joyfully looking at the tetra tank, my sorority betta ten gallon tank and my wife and my faces. I've never had a fish so happy in a small aquarium. He's been in it three days and is still learning his name but hasn't run out of joy yet.
In un-planted tanks it is advisable to use as little gravel as you can, this one's bottom offset is a great guide line for it..
The only bad thing I've found with the tank is that moisture can condense on the little feeding lid and run out onto the top of the tank lid, so give the feeder door a tap or two when you open it.
This tank is a petco product and sold in-store for about $26 to $32 and unless it catches fire or explodes I'm gonna have to give it three thumbs up
