Lightest tank 10+ gallons? Cycle question from re-locating?
I've been through 10 betta deaths thus far, and three were from cancer which i'm assuming was mostly due to BHT and BHA that's put inside Omega One Pellets and Flakes. All of course were in 10 gallon, heated, filtered tanks. I'm trying to invest back into other fish instead.
*What's the lightest possible tank I can get? I prefer trying out 5 or so Rosy Barbs with another kind of tank mate, probably smaller/less waste, and a weather loach or apple snail or something? I like about 11lbs, which is a standard 10 gallon glass aquarium, but I would prefer a bigger tank that stays close to 11lbs. I searched online a few hours for acrylic aquariums but they weigh the same as the glass ones so far. I have to carry my tank down glossed wood steps when I head off, so this is difficult.
I am known for relocating yearly and bringing the entire tank to another location/care taker, or I could re-locate the fish individually. Bear in mind I move them in the dead of winter, all water / equipment can be affected by climate changes, if that kills anything or not I wouldn't know?
I need to know which of these is the better option...
*moving the entire tank with 50% to 10% water, if more than 10% i'd use a bucket.
*moving the fish only into an empty tank without a cycle, but I could add in StartZyme/other similar product
*or neither, should I drop the idea that my fish won't be too safe considering I have to go through this so often?
