Yes a betta fish can go a week with out food. (thats part of what you have to do to breeding bettas). If you want to leave food behind for him when you leave, I strongly suggest against it. This is because leaving food in the tank will (could but this is what I know about from experience) become moldy(green STUFF growing on the tank walls) and kill or become harmfull to your betta. That also goes for any other fish. From now till you leave i suggest feeding as much food as your fish can take. That is the way you prepare for breeding the bettas so that they can go the week or more without food. And no for your bettas I wouldn’t worry about getting someone to watch them, they will do fine. (if you feed them lots before hand, and even then it might not be a problem.)

I agree all the way with the Mr.Cool dude, your betta WILL be fine.

If your betta is in excellent health then yes it can go 7 days without eating. Before you do go out of town do a pretty good water change so that its water stays relatively healthy until you can return.

They will be ok

Goldfish who are only the size of half of a hand aren’t medium sized, they are still very small. Your goldfish will get at least eight inches long, so make sur eyou have at least a 28 gallon if you want a second one. I would only put other goldfish with goldfish. They do well together. I doubt they would eat the other fish, but they dont get along well and the goldies are dirty and could make the other fishies sick.

Anything…I like the black moors. I also like the fancy tailed gold fish. Almost anything is compatible with goldfish.

What you need is an automatic feeder. No, and fish cannot go seven days without food. It’d make them sick, and most fish would die from it.

Hey it is absolutely fine to keep ur fish without food for 7 days. It can even stay for longer. 7 days is not a big period. I can say this confidently since i keep bettas. But still if u have doubt feed him with worms before leaving, and keep some live worms in the tank if ur tank is big or else the water may get spoiled and the fish may die. Infact i have read earlier that u must keep bettas away form food for couple of days to prevent him from putting extra fats.

Refer the site for information below
How long can a betta live without eating? I am not sure exactly how many days, but what I do know is that they can survive without food for a long time. I had a sick betta who ate a half a live worm once a week and lasted three month that way. I know that bagged bettas have been reported to have survived in their sealed bags up to three weeks. So I guess, what I am trying to say is, if you are leaving on a week-end trip and won’t be home to feed your betta for 3 days, don’t sweat it. He won’t starve or anything . Again that does not mean that you should not feed your bettas with punctuality.

It’s best to keep the same species of fish in the tank. So buy more goldfish. Goldfish tend to attack other fish, sometimes kill them. Also, the more goldfish in the tank, the quicker it will get dirty. And if there’s too much of them in the tank, they won’t grow as fast and as big as they should be.

Goldfish can actually live pretty long, provided that you give them the right conditions and everything. =] However, they do require lots of space. As in LOTS!! =]

Bettas actually make great starter fish as they are GORGEOUS and easy to take care of. They don’t require too much space, just 2.5 gallons at least for each. Clown fish are saltwater and harder to maintain. (Wouldn’t recommend it but that’s just me, haha!)

Bettas are very territorial, especially the males. However, this is only a general statement. Bettas have a lot of personality and while one may attack any living thing, another may be more submissive, so it just depends on the betta.

Generally, you shouldn’t put males together in any tank unless you have a divider of some sort. You can put females together in communities if you want though. =] Again, these are general statements. Each betta is different. Between clownfish and betta, I recommend the betta, definitely.

Other fish that I recommend are mollies, platys, and/or guppies. However, these are livebearers, meaning they reproduce like no tomorrow, haha! The females can store sperm for up to 6 batches of fry! So unless you want lots of babies, get males only or females only!! =]

Hope these helped!

Sheesh.. people are giving you good advice here.

Good on you for asking the questions first though..

Instead of thinking type of fish, think about the aquarium ecosystem that you need to run. If you set up the tank correctly and care for it right, then you can keep most common fish.

Now my suggestoin is to go and buy the biggest tank you can afford / justify / fit in the space you have. 15 or 20 gallons is a good size for a beginner. Big enough to actually keep some fish, not so expensive that you cant afford it.

Just buy a complete kit, and a good book on fishkeeping – no fish yet.

Get the tank home, set up and running, and read the book in the meantime. You may wont to do a full fishless cycle on the tank to set it up, but a betta can be added to a tank that size and let the tank cycle in it’s own good time. You than have a tank that you can keep a few other fish in, even with a betta, but never 2 betta in a tank.

You could buy a smaller tank, but that really limits you to a betta only.

Goldfish are perfectly OK, and can live for maybe 20 years, but you will want a larger tank for them. They grow big and are messy fish. If you try and keep them in a bowl, they will die.

Clownfish are tropical marine, expect to spend maybe $1000 on a tank to keep them, and any marine tank needs a lot of research and maintenance.

Good Luck
