i just cant keep my guppies alive

Hi I set up my 23 gallon fresh water community tank about 3 months ago. its near the window and gets natural sunlight all day and i put the light for roughly 4 hrs till i go to bed. i am using an flauvl 303 gravel filter.

I bought 3 tiger barbs and 2 sucking cat fish for my first batch and since have bought 2 silver dollars 2 mollyís and a male and female swordtail. They all live happily with each other. My silver dollars are even happy in such a small group. They arenít shy at all. And my barbs are happy playing with each other (not aggressive towards the other fish at all)

However over the past 3 months a have bought roughly 26 guppies (because I love the look of them and want to try breeding them) but I just canít seem to keep them alive. They never seem to last more than a week. Sometimes only lasting up to 24 hrs.
I have been reading a lot about them trying to find a reason. And I think it may be because I keep my tanks ph at neutral. Iím now worried Iím doing harm to my fish
( which I certainly donít want to do) if i keep my tank more alkaline for my guppies will this affect my other fish?

Thankyou to anyone who can help me.. if you need more information plz let me know.

I didn't see any mention of tank temperature. A stable temperature seems to benefit smaller fish, like guppies. Larger fish tend to be able to tolerate temperature fluctations a little better. Adding aquarium salt, 1Tbsp per 5g of water, is also a benefit to live bearers. If you think that it will harm your other fish, it won't, but use a half dose. It's better than nothing.

I would say that borderline low. I had guppies and can't keep them from multiplying. The pH is fine at 7.0. Salt would make them happier but I don't think some of your other fish would care for it much. Maybe the tank is heating up during the day with the sun and cooling down too low at night? No, that shouldn't do it, my tank at work does that. What are your other levels look like? Guppies are very hardy fish. I wonder if your barbs are killing the guppies. Anyone had the two together? I've very skeptical of barbs.

ohh i actually haven't tested anything else. i only have a ph test kit. should i get one to test everything?? i use a liquid ph test kit.

i hope my barbs aren't hurting my other fish... they seem to get along with everyone though. i've never seem them chase anyone except them selves.

i was hoping to would be off loading my baby guppies to my friends because i have so many not asking for help on keeping them alive. i hate that i cant even keep the easiest fish alive. i love my fish so much and would hate if the things i was doing was hurting them.

which fish do you recommend could be tank mates for my barbs. what do you think about bumblebee gobies??

No fish is easy to keep, nor are they idiot proof. Care must be given and conditions must be met or your fish will not thrive and may possibly die. Fish are no different than keeping a dog. You must take care of it/them.

Don't feel bad..it takes time. I was told to get a certain kind of plant when I was first starting out. You know, those plants that can grow under any condition and never die? Well it didn't last 1 week in my tank! After 4 more tries, I just gave up and got other plants that I have done fine with. Be patience and get a test kit, even strips are cheap and quick althought not always 100% accurate. It's close enough to get an idea.

your tiger barbs are most likely stressing out your guppys and killing them. tiger barbs are aggressive and will chase the tails of the guppys. it does not take much to stress out a guppy i have had this problem once before and got rid or the tiger barbs. now i have about 150 guppys and more every week. started with 3 lol.

how often do you gravel wash/changewater. guppies are delicate fish and a dirty undergravel filter isn't good for them. I change 20% of the water twice a week and the results are amazing. I had trouble keeping kivebearers for a long time, once i started doing this it solved a lot of my problems.
