    Hi friends,

    I have a pair of pleco along with a 2 pair of gold fishes and a pair of shark .

    Recently the I have seen these plecos trying to bite on gold fishes (in a manner trying to stick to them)

    What can be the reason for this??

    I ve also lost one gold fish ever since this started

    Is the pleco turning to be hostile???

    Pls suggest me solution friends.....

    Plecos are never supposed to be with goldfish they eat the slime cost off the goldfish it may take time but they end up injuring the goldfish

    So plecos are not safe for the gold fish to be with???

    Are they the reason for dying gold fishes????

    Should I return the plecos???

    Welcome to fishlore!

    If you can, yes, I would return the plecos. To be honest, I always thought they were commonly kept together, but after a little reading, it turns out this has happened to a lot of other people.

    What size tank are these guys in, and what kind of sharks do you have?

    Some Plecos may be too aggressive to keep with goldfish, or simply like the slime coat's flavor. Plecos really span quite a range in what they eat; some are herbivores, some omnivores, all the way up to carnivores. The different species of this catfish also have differing base dispositions. You really have to research the specific one.

    My tank is a 29 gallon tank

    Your tank sounds pretty overstocked. One goldfish needs at least a 20 gallon tank (most, though, need a 30); then for each additional goldfish, you need another 10 gallons. Also, I can't think of any shark that can fit in anything smaller than a 55 gallon. Finally, common plecos (which I'm assuming is what you have) also need at least a 55 gallon, preferably larger. Sadly, your tank would just be stocked with two goldies.

    Don't be too hard on yourself for loosing a fish- most of us start out this way; it'll get better, I promise! For now, I'd recommend returning all of you fish and starting fresh with fish that are more compatible with your tank size.

    @Dolphinlover101 thanks for your suggestion am planning to reutrn some of my fishes there is no other way for me or else I would have to try a much larger tank sooner..

    If you could post a picture of the sharks, I'd be happy to identify them for you. If you want to keep them, I could recommend what size tank you'd need :)

    You may wanna take a pic of the goldfish too :p Many of them can't be in a 29 gallon tank.

    Common plecos are not as nice and vegetarian as pet shops have you beleive. To at least lessen the amount if times that are bothering the goldfish, be sure you are feeding them enough. Feed them every night if you have to. Just be ready to be doing even more and larger water changes.

    Hi... @dolphinlover101 and @Terra sorry guys am not able to take a pic now at night
    my sharks seem to be too fast for a snap

    I have to get them in net to click a snap

    But recently I searched and found out that my sharks are Iridescent sharks and look exactly like


    I ll post the pics of my gold fishes sooner
  17. Gordinian Well Known Member Member

    Iridescent sharks... Here's an interesting link.


    You would need a HUGE tank to keep these guys- personally, I would return them.

    Does the pleco look like this?


    If so, you'd probably need around a 100 gallon tank, if not larger, to keep the plecos and the goldies (I'd also like to have other members give their opinions).

    Remember to cite photos that aren't your own ;D
  18. MMJ Valued Member Member

    @dolphinlover101 perfect this is the exact type of pleco I have

    I have planned to return them

    they are proving to be very violent towards my Goldies
  19. Gordinian Well Known Member Member

    That sounds like a much easier plan :)

    Are you only keeping the 4 goldfish then? Four would need around a 50-60 gallon, depending on what kind they are.
  20. MMJ Valued Member Member

    I have also planned to change my tank

    So can i know if there are any non aggressive plecos cause I am crazy about having gold and plecos

    Cause i have heard that plecos help to keep the tank glass free from algae

    So suggest me

    I would also like to know if Snails can do the same, at the same time if snails mean any harm to gold fishes???

    And if possible please post the photos of the type of pleco or snail i should prefer, cause here very few people recognize fishes with their exact name
