    I've had my little jack for about 2 months , he's about an inch and a half long and he hasn't really grown at all. Any thoughts?

    Males do not grow more than .25" every 2 months. Clean water, keeping nitrates below 20ppm through water changes and good food will help speed up growth. Being in a stress free environment also helps speed up growth.

    Who are the tank mates? What size is the tank? How do you test for nitrates? What size did you purchase this fish? How long have you had it?

    Ok I didn't know that. I have a electric blue jack dempsey that's growing pretty quick in my 40 gallon. The jack I'm talking about is in a 75 gallon tank with danios , tetras, plecos, and a rainbow shark. I feed him dried shrimp and ciclid pellets

    I've had him for about 2 months and nitrates I normally don't test for.

    It seems like he has grown a little since I got him but not much . The shark does chase him a little but now there's a bunch of giant danios and tetras in there. He may be experiencing some stress but he's very healthy and always comes to the side of the tank when he sees me. I was thinking of switching my electric blue jack and my regular jack to the 40 gallon since it's quite a bit calmer and has just a couple angels in it and 3 rams

    Also.. I don't test for nitrates but I do do water changes every week and the nitrites and ammonia are at 0

    He doesn't look stressed at all in the picture and he seems to come out way more than the Jack Dempsey I kept. I would continue what you're doing. Quality Flake and portions of frozen foods.

    Oh yeah he's a great little fish! I feed him omega super Color ciclid pellets, shrimp and blood worms. I'm just worried he's not growing much. He's very personable and always interacts with me when I come up to the tank. The only stresser he might have is the rainbow shark but that fish is very typical, he hides in a cave mostly and chases anyone who gets to close.

    He's so cute! Have you tried pellet foods? I find larger fish can't get enough nutrition per bite with flakes. I feed all my fish a variety of pellets as a staple, pellet size according to the size of the fish.

    Frozen foods are more of treat for the fish, they are not very high in protein, which your Dempsey will need for growth.

    Some pellet brands I like to use
    New Life Spectrum (start with 0.5mm 'Grow' pellets)
    Omega One
    Fluval Bug Bites (cichlid formula size, red colored container)
    NorthFin (1mm cichlid pellets)
