Our class pet, Buddy, has been staying at the top of the tank and right next to the filter ( not the part that sucked up the water, the upper part) and he just swims there. He is swimming fine and comes out to eat but then goes back. Could it be a traumatic experience? Before my friend and I took over, this guy took care of our three fish, and two of them had been mysteriously shreaded near the filter. Sucked up maybe, we got two more ( Terra and Bubbles) I think he is fine but I just wanted to make sure.
Usually swimming in the flow of the filter or at the tanks surface is an indication of a breathing problem. Either the fish was improperly acclimated into the tank. or there is high ammonia, nitrite or nitrate in the tank.
If acclimation was the problem there is not much you can do for the fish except let him do what makes him feel comfortable.
If toxic levels of ammonia, nitrite, or nitrate is the problem. A 25% water change and a little aquarium salt will help. Other tank inhabitants might not do well with salt in the tank like snails. So check the requirements of your fish before adding salt.
I feel its simply a favourite place of him, may be after some days you will find him out swimming with others.
If the filters suction is too strong for you're fishes I would plug the input tube with a sponge.
1. It decreases flow which is ok
2. It provides surface are to house beneficial bacteria
3. And it will prevent your guppies and future guppy fry from getting sucked up.
The filter sponge plug I used is: a fluval edge pre-filter sponge
I don't think that its a ammonia or nitrate problem because the others are fine, the filter is switched to low. Do you think he is scared? Our class is pretty loud and Terra (one of his tank mates) kind of bullies him, but often joins him in the spot. Another "symptom" might be that everything scares him.
Staying up under the filter is also a sign of stress, if it is being picked on by other fish it will stay tucked up under there to avoid the bullies. When I got my Jake and Elongatus, they both got tormented by some of the others to the point where their caudal fins were eaten down to the stump, now that they have healed they are perfectly fine swimming with the rest.
He doesn't stay like right in the waterfall thing's path, he sort of stays behind the waterfall
Have you checked the water parameters to make sure everything is normal? Also, is he a new introduction or was he added along with thte others? If he was added with the others, it is not likely to be an acclimation issue. Sounds more like a comfort spot or stress. When it swims around are the fins tucked in or are they splayed out?
The water is fine. The others are normal. They go over there sometimes, but don't stay long. He was one of the first in the tank along with his brothers who got shredded. He has been doing it ever since . We added some females and one of them has been like a motherly figure to him trying to get him to come out. Or she is just really clingy. His fins are normal when he swims but the dorsal fin looks kinda shredded on the end.
Sounds to me like the fish is stressed. Your best bet is to move the bully fish to a different tank. Sometimes it helps if you take the bully out for a couple weeks, totally rearrange the tank then reintroduce it.
The only problem is that the bullyfish is pregnant and I don't want to stress her out so it delays her birth...
Hmmm that does pose a bit of a challenge since you dont want to stress the other fish out worse than it already is. What about a divider?
That might help, but we have another female (Bubbles) who gets picked on by the pregnant guppy, so we cant really put her on Terra's ( the bullyfish) side but we don't want anymore fry than we have to have already, since the fish being picked on is a boy (Buddy). Wow, these fish are really making the problem difficult, aren't they?
