Standard size aquarium?

Question

I have a standard size aquarium (25 gallons).Suggest some colourfull fishes for it.In my previous post I was told by 2 persons that 25 gallons is very small for even keeping 2 angel fishes! Is it true?Please suggest some colourfull fishes.Also if I put the lights on for 12 hours, will it heat the water and the fish may die?Which food is better,live or frozen-dried flakes of food?Answer all the questions carefully.

Answer 1

I think any tank under 40 or 50 is really best suited for community fish. Possibly a few cichlids but they are very aggressive so they need their space. You could put a decent school (8 or 10) of some type tetras. There are several species that are colorful such as serpaes, neons (not good in a new tank), cardinals or rummynose. With those, you could add 4 or 5 corys. If you don't do a fishless cycle (link below) then add slowly, with no more than 4 at a time.

And 25 gallons is too small for angels. The grow to about 6" and more importantly about 12 to 16 inches in height for their fins so they not only need a big tank, it also needs to be deep. They are also delicate and need very good water conditions (preferable a lower pH and KH) and a fully cycled tank. Definitely not a fish for cycling.

As for lights, how long you burn them depends on your setup If you have live plants, you need more lighting and higher wattage. If there aren't any plants, you only need to burn your lights when you're there to view the fish. Leaving the lights on too long can promote algae (also make sure the tank isn't in direct sunlight).

A variety of food is best, some flakes and some frozen or freeze dried (my fish never cared for the freeze dried). Just be careful not feed them high protein foods such as blood worms too often as it can cause constipation which can lead to swim bladder disease.

Answer 2

Tetras and barbs are pretty fun tropical fish to keep and they get along well. Don't keep them with less agressive fish though or they will pick on them. Angel fish do need a really large tank because they dirty the water quickly. The lights will not heat the water. If you want tropical fish you must get a heater with a thermostat in it to heat the water. Live and dried food is good for the fish, it just depends on how much you want to pay. In a 25 gallon tank you could keep about ten to fifteen 2 inch long tetras or barbs. Make sure you have a good filtration system to clean and aerate the water.

Answer 3

Yes, a 25 is not large enough for two adult angels. Twelve hours is a fairly long photo-period for any aquarium. However,if your lights are fluorescent,they should not contribute much heat in the tank. Incandescents on the other hand should probably be on about eight hours(two 4 hour shifts would best). As to fish selection, some of the small rainbow fishes would be colorful and active,the larger species would out-grow you tank quickly. Foods should be as varied as possible,with a mix of prepared foods(flakes and frozen) and some live foods(like worms or brine shrimp,or plant materials like zucchini or spinach).Hope this helps.-------PeeTee

Answer 4

I agree with everybody who said tetras. You could get about two groups of schooling fish in there. I think cardinal tetras and neon tetras are very pretty with their blues and reds.

As for lighting, I don't really know how to answer that question. My tank is in my living room, and during the day, I keep my blinds open so I can get enough sunlight into the room (the sun does not hit the tank directly). This method gives them enough light during the day, and it doesn't waste my electricity. When it starts getting hotter is when I am going to start using the lighting.

And food? Most fish will prefer a variety. I feed my danios flake food most of the time and every 3-4 days I will spoil them with a little frozen food. When my tank gets fully stocked, then I will purchase more of a variety of food.

Answer 5

1. yes that is too small for angels, they grow large (5-6" tall) and pairs can get aggressive too. they need minimum 40 gallons for a pair.
2. colourful fish suited to your tank include the following, (if the angels were rehomed and taking into account any other existing tankmates) of course not all in together, but a selection can be considered after researching their specific requirements:
+Guppies
+Platys
+Swordtails
+Cherry Barbs
+Honey Gouramis
+Dwarf Gourami
+Bleeding Heart Tetra
+Cardinal Tetra
+Rummynose Tetra
+Serpae Tetra
+Chain Loach
+Khuli Loach
+Bronze/Albino Corydora
+German Blue Ram
+Bolivian Ram
And I could go on....

3. Only leave the lights on 8 hours max if you don't have live plants, the longer the lights left on, the more algae problems you're going to have. It shouldn't heat the water much.

4. live, frozen and pelleted food are best, fed sparingly through the week and in small amounts. my fish have a starve day once a week.

Answer 6

that is a pretty small tank. really, they are made to hold gold fish or tettras. for that size, yes, one angle fish would be pushing it (they are recommened for about 30gallons).

as for colorful, you'd really want salt water for that. most fresh water fish just arent that colorful. Neon Blue Dwarf Gourami, Opaline Gourami, Pearl Gourami, Golden Lyretail Panchax Killifish, Patrizi Killifish, Boesemani Rainbow, and Praecox Rainbow are some colorful ones, but you'd only have room for 1 or 2 of these at the most. depending on the type, tetras you could get away with having 4 or 5 maybe.

you DO want your water heated. it should be around 65-80 degrees (again, this depends on the type of fish you are keeping) so make sure you have a therometer and/or heater if necessary.

again, depending on the fish will determine what kind of food. like with my old tank (saltwater, but still) i had a tang, who liked alge wafers, or dried alge, my small clown liked freeze dried brine, my gold striped maroon clown liked the freeze dried and live brine. all would eat flake food if given, but it didnt make their colors as vivid.

thats a good site for some ideas, and it tells you how hard it is to keep the fish, how much water is required for 1 fish, the temperature... all that stuff

Answer 7

guppies are nice colourful fish (especially the males)you have to have a ratio of 2 females to 1 male.they are livebearers and havelots of babies.tetras are nice and a tank ful of tigerbarbs is brilliant. you need a heater to hear your water but the light will heat the top. the fish wont die if you keep the temp around 22-28 degrees. flake food is good and some live foods are a great treat.hope i have helped feel free to email me with anymore questions.

Answer 8

25 gal. huh. never saw one, here its 5,10,20,29 etc. If the fish get big, the bigger the tank the bigger they will get. There is a large varity of non aggressive fish that will do well together in a heated tank. You didn't mention the size of the angels, but I don't think thats true unless they are very large. A variety of food is best.

Answer 9

angels grow large and are very agressive,
most lights for aquariums do not produce enough heat to matter. make sure you check temp. regarding food, a little of each-alternate the food.
regarding which fish-go to local pet shop and ask which can go into commuity tank-make sure you discuss with clerk size of tank and filter system you have. then choose which ones you like.
