Will this hurt fish

corbettfam7 · 09-17-2006, 10:18 AM

I just set up my 10 gallon fish tank which i waited 4 weeks to do, and i put three small marble slates in with two plastic plants. Will these marble slates hurt my fish? I'm housing two convick and one pleco.

Note: I also have 75 gallon tank (oscars / pleco)

I don't know of any issues in using marble in the tank, but then again I have not researched everything in this hobby yet. I have not heard that it is bad in tanks (which is generally easier to find out than if it is good) so you may be fine.

Just remember to cycle the tank and check the parameters before adding fish.

Marble will cause an increase in KH (water hardness). It will also effect pH somewhat. Really depends on your fish, critters, and plants tolerance/preference for hard water.

I would take a KH GH pH reading now and then in two weeks to see the impact. Then make a decision.

Incidentally, in this thread initiated by You, rocks, including marble, were thoroughly discussed.

You know what jay, your right this was talked about. So i will remove the marble, don't want to cause any harm to my new fish.

Thanks

Convicts are very tough little guys, whatever changes in water parameters marble may cause is not likely to bother them one bit! I think it's pretty safe to say that the same probably goes for your pleco too.

I do think that your 10g is going to get too crowded pretty quick though. A pair of convicts would be a lot better off in a 20 long. Also, if they're a male and female, it's likely they will not tolerate having any tank mates in there with them once they decide to breed, which usually doesn't take long and never seems to stop after that

Thanks alot for that information, this 10 gallon tank was going to be used as an holding tank (for feeder fish) until i found out that it was a bad idea to keep feeding my oscar live fish. That's when i put the convicts and the pleco in, and by the way after about three weeks the convicts started breeding. And i don't know what to do with the babies?, I will place a post on the forum and see if anyone have some ideas.

Well, the Convict fry would make a tasty treat for your Oscar, especially if you were planning on giving him feeders from the get go. I thought feeding a fish like an oscar too much live food was only considered bad because it would spoil him into not eating anything else, though I could be wrong about that.

I think the biggest point about not feeding live fish as food is that you cannot guarantee your Oscar's safety and health. Basically, you do not know how healthy the food is unless you quarenteen it long enough and by then, your Oscar is going to be pretty darn hungry.

I have also heard that colorful fish, such as goldfish and mollies/platties can cause liver problems in fish. I know that almost every where I have read on the subject states that goldfish in particular are just host to too many diseases and problems to be really good and viable food source.
