I just set up our new 75 gallon tank. The tank is newly planted with sand, slate, drift wood, 300 watt heater, and led light. We will be using this tank for community fish but will not have the filter for another month. I'm wondering if my very active betta that's in a 2.5 gal tank would be ok to put in there? My concern is the depth as its 18" tall and I know bettas like "puddles".
We don't plan on keeping him in there as the filter will be way to powerfull for him but I figured he could spend a month in there and can help contribute a microscopic amount to establishing the tank haha. Also the 2.5 he's in now doesn't have a heater and our house is getting cold at night and the 75 has a heater already. (I'm picking a heater up forthr small tank in a few days)
Again, you might be able to keep him in there if you have a comunity going in it. but as a permenant thing by himself... that's just too stinking big!!! but if that is the only tank with a heater, then focus on his health, not his comfort, which means that he will be put in there despite what he desires. it does no good to worry about him being pretty if he is dead from the cold. sorry for being blunt! and yes, he will help a little to cycle that massive tank. and who knows, he may like it!
Without a filter in there the tank won't cycle in any event.
Personally I would just get a heater for his tank and leave him be. Switching him from one tank to another and then back again is probably gonna stress him out, and a stressed out betta is much more likely to develop health issues.
Hi, everyone has given you excellent advise, and I may be stepping out of line here, but that filter you are planning to get is not planted tank friendly. The fx5 is better suited for an African Rift lake type of setup. The currents it produces are substantial, and in a planted tank, it would be overkill... in my humble opinion. Congrats on the 75!
