benno Posted March 2, 2005 Share Posted March 2, 2005 Is it true that a fish in a bigger deeper tank will grow quicker than a fish in a smaller tank with both getting the same types of food and the same amounts of food. I know its a pointless question but ive heard so many different things on this topic id like to hear from you guys. Benno Link to comment Share on other sites More sharing options...
Burek Posted March 2, 2005 Share Posted March 2, 2005 I dont really know. But i think they grow a bit quicker in a biger tank, but the majour difference is that they will grow much bigger in a bigger tank. HTH - Cheers Daniel Link to comment Share on other sites More sharing options...
Ducksta Posted March 3, 2005 Share Posted March 3, 2005 I think the truth to it is based on the fact fish will grow faster in better water conditions. If you have an overcrowded small tank, water will be fouled quicker. Link to comment Share on other sites More sharing options...
Chilli Powder Posted March 3, 2005 Share Posted March 3, 2005 Fish will grow better in tanks with large surface area, good water conditions and good food. Link to comment Share on other sites More sharing options...
YeW Posted March 3, 2005 Share Posted March 3, 2005 In a larger tank you have a greater volume. Duck's right - higher volumes decrease (by dilution) the compounds that slow fish growth. Link to comment Share on other sites More sharing options...
r.d.m Posted March 3, 2005 Share Posted March 3, 2005 also on yew and duckstas answers its a well known fact that big koi release a growth inhibitor into the water -small fish = small appetite, this has also been observed in other species , so a big tank would dilute this and shows that water changes remove more than just nitrate, ive also noticed that with 50% weekly water changes on my fry tank (rather than 25%) the growth rate has increased, so big tanks with regular water changes= big fish Link to comment Share on other sites More sharing options...
Fins Posted March 3, 2005 Share Posted March 3, 2005 so big tanks with regular water changes= big fish faster well said rdm Link to comment Share on other sites More sharing options...
dobbin4 Posted March 3, 2005 Share Posted March 3, 2005 Big tanks with larger surface area & good water conditions =faster growth. But u can have[ small fry] small tank and good water conditions that grow as fast.Thats what i find.John Link to comment Share on other sites More sharing options...
ViS Posted March 3, 2005 Share Posted March 3, 2005 Another twist is how I grow my fry. I have large surface area fry tanks (4ft x 14in or 18in floor) but they are only 6-8 in high. This way, the turnover rate is 2 or 3 times that of a standard 4ft tank. The tanks are connected to the central sump and get a high flow rate (equivalent to what I'd put into a normal 4ft). This seems to work well, and I reckon much better than a deep tank, as they are getting more clean filtered water from the sump than they would otherwise, as the "old" water gets returned to the sump much faster.

benno Posted March 3, 2005 Author Share Posted March 3, 2005 Thanx guys i was just interested in what everyones thoughts were. Benno Link to comment Share on other sites More sharing options...
r.d.m Posted March 4, 2005 Share Posted March 4, 2005 andy , do you think deep water makes fish feel more secure? there must be swim bladder issues as well, you hardly ever see fish in the wild in 18 inches of water apart from trout, and i believe fronnies are found in no less than 60ft of water Link to comment Share on other sites More sharing options...
