    Is this fry fat, or does it have worms?

    Hi everyone, last Saturday I went by a nearby lfs and bought 3 ottos. Upon arrival at home I noticed a small, unknown fry in the bag.

    Hi everyone, I purchased 6 Discus about 5 weeks ago in my 75 gallon aquarium. Everything in the tanks is going well; the chemistry is good (pH: 6.5, hardness: 25, Nitrate: 5, carbonate: 20) and all fish are growing fast and healthy. But one discus, pictured below, seems to be a little skinnier...

I have flatworms and detritus worms all over the glass, plus little white specks that dart around, and some grammarus or something living in the sand. Mostly I just want to get rid of the worms.

    Found worms?

    I am just setting up a new bristle nose breeding tank and as I was moving wood and plants from my old tank I found these. I have no idea what they are. Are they parasites or unsafe? Are they safe for fish?

    Hello I am fairly new to this forum, I am now a owner of four male guppies. They live in a 6.7 gallon tank and unfortunately I feel like it’s my fault for not noticing that when I brought my three new fish to add to the tank one of them was acting odd. I’m talking about swimming by the filter...

    Just in case it’s worms... should I treat the tank

    As some of you have advised me before you might remember I have some trouble with my guppies. My first batch of guppies have progressively sickened and died with just 1 remaining of the first 6 after 4 months. The first 3 deaths I put down to ammonia spikes as I struggled to keep my water...
