Keeping dart frogs with day geckos ???

but water feature means running water with filtration right ?? i' ve always kept my bettas in 1 gallon tank without any filters or bubbles all i've got is some ''mousse de russie'' (moss ball in english i think) or other living plants as filtration ... and they don't breathe the oxygen in the water: if you put a betta in a large tank like 15 gallons it will drown because he'll soon be too tired to swim all the way up to the surface to breathe...

Hmm that doesnt sound right to me...You do realize people who breed bettas use much larger tanks then 15 galons..And in the wild they have entire rice patties to swim around in. I understand they need to surface, but as Beck said, the frequency depends on the water quality.

anabantids have gills as they're primary means of respiration. i believe they've developed their labarynths over the generations as means to breathe under extreme conditions (as in during the off season when the rice paddies are run almost dry). their gills are still their primary means of respiration.

i had a betta in my 50 gallon community tank with guppies and everything else for a while. when she died it was due to an ammonia spike, not because she couldn't get to the top. there were days when she zipped around the tank like she just drank a whole pot of coffee. there were other days when she just went about her leisure and layed on anything she could lean against or tucked under whatever she could get into. she loved to wedge herself into things she couldn't get out of and there were plenty of times she used the current from the filter intake to rest on. my brother-in-law has freaked at least a dozen times thinking my fish was dead. talk about hilarious... and annoying, lol.

one thing that's lacking in most betta setups due to the common misconception they can be kept in a coffee cup is adequate cover. bettas, ime enjoy the cover or the nice, soft resting spot provided by some nice sturdy wide leaf plants like anubias bartieri, amazon swords or cryptocoryne wendtii. they'll also swim themselves into the tightest constrictive area they can fit into and rest there for hours... sometimes days on end... for no apparent reason. all this simply cannot be provided in under a gallon of water and even that would prove to be quite difficult to pull off unless you choose your plants/furnishings wisely. if one were to pull it off it's still likely that either filtration would be inadequate or the fish would constantly (which is key to avoid) be battling the current from the filter with no place to escape.

there simply is no fish that is not effected by ammonia therefore at the minimum moving, oxygenated water is a necessity in any aquarium.

well i've kept female bettas (6) in my 20 gallons no problems but my male died in a 15 gallons and i attempted breeding them in the 15 gallons half full and it didn't worked then i tried them in my 10 Liters tank and it worked.... i guess it depends on the lineage of the betta
