I recently inherited about 30 adult guppies and put them into my 20gal tank. They are all a little stressed and I realize very overcrowded, but are generally doing good.
My problem is I am going away for about a week and I am trying to decide whether to use an automatic fish food dispensor or one of those vacation pyramid feeders.
I have used those feeders in my other tank with no problems, but they have been known to change to PH which is what my new fish don't need right now.
Have any of you had problems with the vacation feeders? Lost any fish after using them?
Also some books say gups and even the fry can go two weeks without being fed---
I don't know about that.., though I guess it's better than being overfed by a neighbor...
any help would be much appreciated as I am leaving very soon...
