Hello friends,
I currently have a betta in a filtered 5 gallon tank. Today, I found a 10 gallon tank at a garage sale with necessary accessories for $5 and my original plan was to move my betta into that tank and add some better substrate and plant it... but then I got to thinking, maybe I could just plant the 5 gallon and add something more fun to the 10 gallon... or I could add my betta and a couple corydoras to the 10 gallon... so many options! He's a pretty laid-back betta so I suspect he may be okay with other fish, but obviously don't know. Any input on what I should do with my new tank that would be both fun to look at and easy to maintain for a relative beginner?

10 gallon is too small for cory cats really.
>>
>>3148308
If I go that route, what would you recommend putting in the 10 gallon that would be visually appealing and fun to idly watch (it will be on my desk which is quite large) and manageable for a beginner? Also my bad, I rarely come here and didn't know there was an aquarium general thread

Do you think a beginner could successfully plant a 5-gallon without it turning to shit? Any tips or things I should research? I'm not looking for people here to do all the legwork for me but some starting points would be greatly appreciated
>>
>>3148310
I've heard that pygmy corys are okay in a 10-gallon and there is a local specialty aquarium shop so I will see if I can get those specifically (or go to a nearby larger city). Still a bad idea?
>>
>>3148312
Pygmies might work, but you need more than 3 for a proper school. Even the commonly cited 6 minimum really won't bring out their best and natural behavior, it takes double digits to really get them comfy. I mean, you can deffo keep them alive, but personally, I just think it's cruel to deny a schooling fish a proper school.

my dog recently died and my wife really wanted a pet to replace it. my coworker had young kittens and i foolishly told my wife about it. she went and got one while i was at work today. it's very young and kinda scared but already likes being pet and seeks it out.

what kinda cat is it?

Polars are literally pure predators. Their dentition and nails are solely adapted to kill animals with layers upon layers of fat. If a polar wants to kill a brown its going to do it

Fuck polar bears. They eat seals and seals are cute. I doubt a grizz could take one. A kodiak more like.

To be fair to polar bears, seals look delicious. I'd eat them too. You can't tell me this doesn't make you hungry just looking at it.

>a flat Earth tier retard who is unable to support his arguments with either any cited research and can't even paraphrase points

>I'm just interested in the facts and you've been awful at providing them.

Your mistake is thinking I'm arguing with you (I am not). Or that I'm doing anything other than providing facts.

Not only should you read all sides of an argument, but you should criticize all sides. And once that's done you can go right ahead and NOT take a fucking side because you're not an expert.

And that's exactly what you'd do if you were
1. actually interested in facts
2. capable of finding papers
>>
>>3148014
all the relevant citations can be found on Wikipedia below the Komodo Dragon article.

that's exactly where one half of this conversation gets all their information. Wikipedia that is, not the citations.
>>
>>3147985
It's also worth knowing that if the prey dies on a timetable consistent with shock and exsanguination that would discredit venom as well as sepsis.

If dragons were venomous we'd expect faster death. If the animal were septic we'd expect the same. If the death occurs at the same speed as death by any other ambush and wait predator the dragon is neither particularly venomous nor particularly septic.

>Isn't this the case for a lot of lizards?
I honestly don't know. I don't think most lizards are hypercarnivorous though. So even if true it's possible it serves a different purpose in varanids.
