Do betta's sleep... i noticed that jasper lies down alot on the bottom of the tank, is he sleeping or is something else wrong with him...
i just bought a new heater for my jasper today, it's one of those you set the temp. on it, a theo hydro 25W heater. i put it in the water for the first few seconds, power off, so he can poke at it without getting burned (betta's are curious fish... ). then i turned it on, by now i don't think he notices it, i do tho it's getting a bit crowded in there with the filter the thermometer and the new heater (next step is a 5 gallon glass tank..the people at the pet stores say glass tanks are better then acrylic ones...
do you think it's the heater making him feel down.. the lack of space.. or his he just really tired...
