jace1969 Posted October 27, 2021 Share Posted October 27, 2021 I have been given a tank,its 20 inches long and 13inches high with a plastic top with alight (which don't work)i had a aquarium years ago like 30 plus. All i want to put in is goldfish nothing that needs loads of care,i was going to put gravel in it and a little stuff to make it look nice but the question is. Do i need a pump being goldfish and can i just use normal tap water and leave it settle and how about a heater for the water. Sorry for being a bit thick on this but aint dealt with fish for ages.

Jimpster Posted October 27, 2021 Share Posted October 27, 2021 One or two goldfish will be fine in a tank of that size. You should never use plain tap water for fish of any kind. Putting in some oxygenating plants and possibly a small flual type filter will help keep the water clear. If you put a heater in they may grow bigger and faster but it will also shorten thier lives. Change no-more than a 1/3 of the tank per week on any one water change, put the water in a bucket and allow the chill to go off it for a few hours before adding. Hope that helps. Ive had goldfish right up to Discus as per my avatar, yes that was one of mine. good Luck. 2 Quote Link to comment Share on other sites More sharing options...
Turvey Posted October 27, 2021 Share Posted October 27, 2021 Agree with @JImpster definitely need a filter, goldfish are notorious poopers! Ideally you would want to get the tank and filter through the nitrate/nitrite cycle first, well you do with more sensitive fish anyway. If you've done that, with water changes I leave the fresh water in a bucket with a small recirculating pump in it overnight to get it up to room temperature. Alternatively/as well you can add treatment to it to get rid of the chlorine. Disclaimer: I have never kept goldfish but have had a few tanks with tropicals over the years and now have a couple of non-heated tanks including one with about 15 white cloud mountain minnows which I have managed to bring on from spawning. 1 Quote Link to comment Share on other sites More sharing options...
jace1969 Posted October 27, 2021 Author Share Posted October 27, 2021 Thanks for the advice,just filled it full of water just to test for leaks and all fine. I will get some gravel and some plants from our local shop,i have also seen online a colour bubble light like a round thing so fits in the bottom with LED lights and gives out bubbles. Because i have had it given me i dont want to spend over the top on stuff but then again want to do it right as i don't want to kill them and would get about 3 or 4 . So you can still get the tablets to make the water better stil,get some of them as well. 1 Quote Link to comment Share on other sites More sharing options...
Turvey Posted October 28, 2021 Share Posted October 28, 2021 This is the stuff I use, just measure the amount you need. Personally I would think 2 fish would be enough for a tank that size as any more would start to be overcrowded when they start to grow. 2 Quote Link to comment Share on other sites More sharing options...

SussyBaka Posted November 8, 2021 Share Posted November 8, 2021 I think heater wont be needed and do use a tap water conditioner before placing the fish rest is all upto you for decoration purposes, like hydra or any aquatic plants to replace a water filter 1 Quote Link to comment Share on other sites More sharing options...
