Full Moon?

[PsiPro]

OK So last night my girlfriend called me and told me her pleco swam up the outflow of her [acronym:38351dbcda="Hang On Back"]HOB[/acronym:38351dbcda] filter and tried to get under the biowheel. It didn't work.

Today when I woke up I couldn't find the guppy I had in this tank (he is a new transfer from my community, same water). I looked everywhere and eventually found him in the [acronym:38351dbcda="Hang On Back"]HOB[/acronym:38351dbcda] filter, on the back side of the filter media.... There is no way he got in through the intake, and I do not have the lid on the filter, so i'm assuming he jumped up the outake then over the filter. I do not have a lid on my filter so its possible i guess. This scenario makes sense as I heard alot of splashing last night comming from the tank, but at the time couldn't identify it.

Why would they decide to to this? Seems like an odd behavior to me.

Ok, is this some kinda Finding Nemo joke?

Some fish are just goofy that way. I've had a danio end up in there by swimming upstream and a baby swotrdail and a baby guppy go through the uptube. They are all fine now. Maybe he was homesick and trying to find his other tank.

Was there any gravel in your filter?

some fish are jumpers, and will do so when water conditions aren't right. Possibly the water fresh out of the filter was "better" to him (more [acronym:22583ff142="Oxygen"]O2[/acronym:22583ff142] possibly), and he wanted to go there.

Especially shrimp and young fish seem to like the debris in the filter material. It's their kind of food I think.

Some fishes will still jump, even if the water parameters are good! Maybe he didn't get along with the fish in the tank. My guppies always loved the current, in the wild it will make them jump upstream.

[PsiPro]

No, this is real, but it is very like Nemo.

There is no gravel in the filter, its just some of the Carbon that fell out.

I think the poor water is a probability for my tank (the params are OK but somthign about the tank rubs me the wrong way i guess), but not for my GF's tank.

In this tank there is 1 guppie, and mabey... 2 ghost shirmp? Soon there will be some Cherry Reds in the tank and the guppy can go home, he is there mostly to increase the bioload so I can toss the shrimp in there with litttle worry of increasing bioload.

I've always said that trying to think like a fish gives me a headache. Many fish (especially live bearers), are natural jumpers. The only way to prevent this is to make sure the lids on your tank are properly fitted.

[Tiffi]

Yes, properly fitted lids are absoulutely nesseccary in most cases (e.g.shrimps, hatchetfish, livebearers, many other fish). It can't be you tank mates, so I guess either your guppy decides for suicide or he just felt the natural call to jump (well, or maybe it's the water if you say it yourself).

The tanks has previously been used only for plants and the ghost shirmp. I add quite a bit of food (intentional overfeeding) to help the snail population boom. Other then that the walls were covered with alge untill i scraped it off. I didn't mind the green walls becasue it helped the shimp. I dunnoo, all the water comes strait outta the community tank to keep the shimp happy.

I dunno, I'll work on rigging up a lid, or rather a retaining wall for the shrimp. proaly gonna have to be something cardbord for this tank but i'll get it workin.
