Question how many hydras is too many hydras?



hi everyone I need your help from those of you who have had experience with hydras Im wondering when do they become dangerous or if they even are dangerous. Their weird little things and they are everywhere I look in my aquarium. The fish dont bother with them sometimes they eat them but Im not sure.

thank you for your advice:)

I'm not sure how many is too much but years ago I had hydra in my 55 gallon and I worked at a pet store at the time so I asked a co-worker and he said just get two gold gouramis and don't feed them and they'll take care of it. I don't remember how long it took but they did take care of the problem.

Sometimes the "cure" can be worse than the initial problem. I never recommend acquiring a particular fish just to solve some issue. The safer course is to fix the cause. In this case I can't offer much on that, because to my knowledge I have never had hydra, though with my eyesight I might not see them anyway. I know there is an incredible amount of live creatures in my tanks; the fact that so many fry can hatch and survive when I am certainly not feeding them is proof of this.

Gold gourami [which is the "gold" variety of the common Blue Gourami] do get large, and can be nasty to certain other fish, especially in small quarters. I would not suggest acquiring one (or even worse, two, as they are territorial) unless you have a large tank with suitable fittings for these beautiful fish.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

yeah they are tiny tiny these odd little creatures.

I now am feading the aquarium once a day because it seems that everyone is getting fat from eating all the tiny little creatures that live there..its crazy how many there are! do you think that they can get enough nutrients from them to not need regular food? I gave them shrimp today and the all went nuts! even the tiniest one that barely eats!

yeah ill just see what happens I mean they are just taking over every surface..even the glass!

Hydras are only a danger to small fish (under 1/4 inch). They can harass slightly larger ones, but you'd notice red spots where your fish were stung.

If you decide to get rid of them, then I would manually remove as many as possible and use an anti-parasite remedy.
