I have a small school of tiger barbs and while feeding today I noticed one of the juveniles swimming frantically, diving head first into the sand, swimming on its side. I'm new to these fish and don't know if there is any special disease that affects them. I gave him a salt bath for a few minutes, he is currently in a bucket that has about 0.5-1.0 gallons of water in it so he can reach the surface easily. I just dosed the tank with an anti-parasitic today, is it related to that? The normal tank is at 78°f and the bucket is at 80°f. There are leaves and floating plants in there, I dosed with kanaplex and metroplex. What else can I do?

I just added a blue paradise male gourami to my 40 gallon (breeder) community tank. I noticed that he is being aggressive to the barbs and corydoras in the tank. I have him, two female dwarf neon blues, 13 kuhli loaches, 3 horseface loaches, 8 corydoras, 5 tiger barbs, 4 bumblebee gobies, 4 pea puffers, 2 blue stiphodon gobies, some ghost shrimp, and 7 otocinclus's. The tank is fully live planted with a good sized cave-like structure in the middle. Everybody is chilled besides him. The pea puffers show little aggression to each other, let alone anyone else. The tiger barbs only chase eachother, and everyone acts civil, even during feeding time when they are really excited. I noticed this behavior yesterday and immediately separated him into a breeder box. Turns out, dwarfs and paradise gouramis can't go together, which I didn't know. Yes, I did look into this fish beforehand, but all my sources failed to tell me that they can be aggressive little shits, especially to 'soft finned' fish like gouramis. I have another cycled tank, but that houses my Betta in it who is aggressive to fish that aren't loaches and corys. Should I return him or do I get some females to calm him down a bit? I am more than willing to learn and do what's best for my fish. If you think returning is the best option, please let me know and share your experiences, good or bad. I'm currently on the way to school so I will get a picture and some fresh peramaters when I get home around noon. Thanks!

TLDR; Male paradise gourami being mean to other tank mates, wondering if I should return or if adding some females will help. Kinda attached to him already

I have three gouramis, two female dwarf neon blues and one male blue paradise gourami. I just bought the male yesterday and I realized that he is chasing the corys and barbs. I have a giant cave-like structure in the middle of the tank and a bunch of plants. Lots are still growing in but there is lots of floor coverage with java ferns galore growing in. There are lots of crevices to hide in. I don't know why he's being so aggressive. Also, can two gourami species breed and make fish mutts?

I have four true freshwater bumblebee gobies, and they are extremely picky. They live with pea puffers, and before you come at me for incompatible fish, they are chill with each other. I have seen the puffers and the gobies both go into a feeding frenzy and leave each other alone. Back on track, I have a 2.5 that I breed ramshorn snails for my puffers, and I recently discovered I have thousands of detritus worms in that tank, so I sucked some up for feeding last night, just to try out, and they loved it. They ate tons of food and it was the first time since I noticed that they wouldn't eat frozen that I was sure they had a good meal. I figured that they were eating my baby neocaridinas as my population was decreasing, so I moved the shrimp to my other tank. I just want to make sure that detritus worms are a suitable food for them. The snail (and now worm) tank gets fed algae wafers, carnivore wafers (krill and spirulina as main ingredients) calcium chunks, and sometimes frozen thawed krill and brine shrimp. They get high light as well.
