15 Gallonwhat Would Be Best?

[jess6905]

i just recently got a 15 gallon tank and was wondering what would go well in it. i have always wanted angelfish but have been told that they will out grow a small tank too quickly. i could always give them to my dad who has a tank that is atleat 30 gallons, but he has agreed to keep my sun cat in there when it out grows its current home would that present a problem??.... i have also been considering gromis, or even rainbow fish, but what could i put in with them?? i want to put my 2 cory cats and sun cat in there to start with. the sun cat will only be in there for afew months though. i already have 21 bettas plus thier fry, 14 goldfish, and guppies so i dont want any of them for in this tank. what recomendations do you guys have?? if what i am considering wont work for this tank then what else could i put in it?? i wont be adding any more fish for probably a month or so, but i want to get input while im getting the tank ready.

It would be best to keep any larger fish in a proper size tank for it to live out it's full adult life, any smaller and you run a very high chance of stunting them. In the case of a few slow growers, you can get away with keeping them in slightly smaller than minimum tanks for a while.

30 gallons will be far too small for a fully grown sun cat, those things get over a foot, 8 inches would be on the small side for a sun cat. I wouldn't put one in anything less than 75 gallons, they also shouldn't be kept with fish smaller than themselves as they're carnivores, that would inculde your corydoras. I'd suggest rehoming him while he's smaller as it will be much easier. It would also be on the small side for an angelfish, especially if he's already got other fish in there.

Going by the info in your profile (correct me if this is different now), I'm afraid 30 gallons is also the bare minimum for a single fancy goldfish, possibly two. With 14 in there you will experience problems, I'd rehome 12 of them if they're fancies, all if they're comets, shubunkins or commons. Plecos are also potentially large if you've got a common or sailfin and will need 75 gallons minimum (though I'd say that's still on the small side), so hopefully you can sort those out as well.

Seeing as you'll need a lot of space for those betta fry to grow out in, depending on how many you have, I'd use the 15 gallon for that purpose for now and sort out your other stocking first. For a permanent community tank, check out this topic on fish suitable for a ten gallon. 15 gallons isn't a whole lot of space, I'd treat stocking the same way I'd treat stocking in a ten gallon, except with a bit of extra room for larger groups of shoaling fish. There are some fun oddballs as well which would be a bit more work, but you could keep a small brackish tank with bumblebee gobies or maybe three dwarf puffers in a species tank.

my goldfish have been in the 30 gallon for over 1 year now and are doing great with no problems. when i can make more space, and get enough cash they will either all be upgraded or i will split them up into much smaller groups. also i have and still am considering rehoming afew of them.

i know how big he will get, and am aware that he is a carnivore. i did do some reserch before i bought him. as for the corydoras they can stay in the sorority tank they are already in. by the way i took another look at my dads tank today, and it is bigger than 30 gallons.

i already have 2 10 gallon tanks for growing the fry out in, and have considered that as an option aswell.
thank you for replying aswell as for your concern. if anyone else has an opinion that they would like to share then by all means please do so.
