    Is there any pleco that dosent grow to big for a 20 gallon i used to have a bristlenose pleco but he literally kept attacking and trying to latch on to my cory catfishs and I always fed him algea wafers and boiled carrots and flakes but he was always so aggressive so I don't think bristlenose plecos would be a option

    Mainly, all plecos need 30 gallons because of their size.
    Even the smallest plecos need 30 gallons or more.

    I would think you could get away with a BN pleco in a 20 long but not a regular 20. The footprint of the tank would allow it but the footprint of a regular 20 would make it really hard on the pleco.

    I'd pass on a BN with the 20g long.
    TexasDomer was the one who personally told me.

    I think I will wait to I mean I already have a small dojo and 3 corys so I think I have enough bottom feeders might add though another cory or 2

    Yes, Cory's need a school of 6, preferably more.

    If you need a fish to provide the algae eating services of plecos, Otocinclus would be a good addition. They stay very small and won't uproot all your plants like Plecos will.

    I understand that. My entire tank is bottom feeders except two guppies lol. I have 2 lemon BN plecos, 4 mystery snails and about 20 RCS...and the two guppies and I'm about to move them out to a 20 gallon when I get all my stuff together and get the want to so the kids can watch them have a breeding and birthing good time lol.

    I haven't had a pleco uproot a plant ever and my tank is fairly well planted.

    Remember that the Otocinclus are almost always wild caught. So quarantine and I preventative treat with PraziPro. They have a high death rate because it's hard for them to acclimate to captive food. Cucumbers, lettuce, zucchini are your go to foods.
