New Tank Fish Compatibility

[ladycage]

I have a 10 gallon tank with one male betta, one pink cory
cat, two painted tetra, 3 swordtail and 3 mickey mouse platy. I think
the painted tetra maybe harassing the mickey mouse because they are
chasing them around, I thought they were compatible but one of my mickey
mouse ended up dead so now I just have two. Should I take the painted
tetra out and put in a separate tank, if so what is the least amount of
water they need since I don't have alot of space.


Can they all eat the same food? Tetra Min flakes, Pellets, Wardley tiny freeze dried shrimp, Wardley shrimp pellet formula

What do you mean by pink cory cat?
Corydoras should be kept in groups of 6 or more.

mlawson is correct. You should maybe think about re-arranging your stocking a little bit as you are overstocked and it sounds like its causing some problems with the inhabitants! Ideally you should just return the tetras to the LFS and probably a few of the other fish too. Having too many in a small aquarium will cause stress, fighting, and ultimately disease and death. If you only have 1 cory, you should return him as well - he is probably lonely. Sorry to be the bearer of bad news, but Im sure some other members will also chime in.
On a bright note, the feeding looks good. Im assuming the shrimp pellets sink which is good for the cory, he needs a sinking food.
HTH and let us know what you decide to do.
P.S. Welcome to the forum!!

yeah the cories and the tetra's both prefer to be kept in groups of 6+, because they're not happy they're lashing out and this is causing your problems. however you're overstocked as it is so you can't just put some more in. you need to take something out.

also what's the ratio of male and femal platys and swordies, getting this wrong can cause stress

I have all male swordtails and I am not sure about the others but I think they are male. The albino cory cat seems fine and I seem to like him, he is very vibrate and active. I have another 2.5 gallon tank with a male betta, 1 painted tetra and 5 small zebra danio and 1 albino cat cory. that cat cory is not attractive at all.

What do yor recommend for my 10 gallon tank with one male betta? what other fish and how many can I have in that tank.

Thanks for your help. Oh I have rock gravel and a aquaclear 20 filter and a heater.

 

[Miss Wiggle]

with a male betta, honestly nothing. i believe they do much better kept in tanks of they're own!

if you put the cories in a group of 6+ you'd soon see how much more active and happy they'd be!

Well, first of all I would take all the fish out of your 2.5g except the betta --- he is the only one that fits in there!! Danios love to swim back and forth and ideally need a 20G. You should put both your cories together since they like each others company.
Back to your 10! The generally rule fo thumb for fish is 1" per gallon. So you can ideally have about 10 inches of small fish in your 10- gallon! Your betta takes up about 3". Giving you about 7" to work with. So you can keep either the swordtails or the platties. Assuming you keep up on your water changes and are over filtered you could overstock a bit and keep the 2 cories in there as well.
Hope this helps!

One of the swordtails has lost its tail, looks like it was bit off, have you ever heard of them biting each others tail off?

Lady - as we've mentioned, this tank is overstocked which is causing stress on the fish. Stress leads to lashing out and YES they can and will attack each other. Please think about re-homing some of these fish or they may all end up injured or dead.
What have you decided to do with your 5 G?

Losing its tail can also be due to finrot, again often associated with overstocking.

If you can get anyone to take the swordtails in their present condition, IMO they are the ones that ought to go. I don't think you should ever keep swordtails in less than a 3 ft tank, it's just cruel with such big active fish. I would also find another home for the danios, for the reasons mentioned by Breeze. In fact all I would keep would be:

in the 2.5 gallon one male betta on his own.

in the 10 gallon the other male betta and either 3 cories or 3 platies (assuming that the betta shows no aggression towards the platies).
