Regular Member Phillyn17 Posted July 22, 2013 Regular Member Share Posted July 22, 2013 (edited) Hi Karen... The generally accepted rule on Koko's is 15-20 galls for the first fish, and 15-20 for every fish there after. I have heard of the 2-3 galls per inch of fish rule of thumb also....but obviously I would have to advise the Koko rule first and foremost. BTW .... How long/big is the resident "Old timer"?

Regular Member DieselPlower Posted July 22, 2013 Regular Member Share Posted July 22, 2013 What is your filtration and water change routine like? Sent from my iPad using Tapatalk 2 That is a good question. Personally I think that is enough water for 2 fish but I don't really think it is enough space. Does that make sense? With a good maintenance routine I think it could be done and I also think hour current fish would propably appreciate a friend. What are the dimensions of this tank? 0 Quote Link to comment Share on other sites More sharing options...
Regular Member cmclien Posted July 22, 2013 Regular Member Share Posted July 22, 2013 I think two is workable if you have at least 10x turnover on your filters i.e., 300gph filtration and large water changes (more than 50 percent weekly). Make sure if you decide to add one to quarantine the new one for up to a month so you don't bring unwanted disease or pests into your tank.

Supporter Daniel E. Posted July 22, 2013 Supporter Share Posted July 22, 2013 I think two in a 30 will work in most cases with proper care now there is the monster fish that some grow into that might make you need to upgrade in the future. But 2 is a good number for a 30. I have 2 in a 29 right now (still small) but still two will be adding a 3rd short term while I'm looking for a bigger tank. 45-50 gal for a long term home.

Karen, i just wanted to advise, should you decide from advice given here that you would like to introduce another fish to your established tank, we here strongly recommend a QT period minimum of 4 weeks for the new fish. so, you will need a 10 gallon tank/tub, spare filter and if needed, a heater so that you can treat your new fish with salt & Praziquantel. the reasons why we do this is because nowdays, a new fish will most likely have flukes, possible beginnings of Ich and/or internal parasites which could contaminate your 5 year old. 0 Quote Link to comment Share on other sites More sharing options...

Regular Member dnalex Posted July 22, 2013 Regular Member Share Posted July 22, 2013 Hi Karen, I would say that by this point, I would not add anything to the tank. Five years is a very respectable amount of time, and there is no reason why he/she should not go for ten more. When you add any other live creature to the tank, you risk destroying the established ecosystem, and this could threaten your fish's health. To me, it's not worth it. It's not about whether you have space or not, but all about keeping a great thing going. 0 Quote Link to comment Share on other sites More sharing options...
Regular Member shakaho Posted July 22, 2013 Regular Member Share Posted July 22, 2013 Alex makes a very good point. I agree. But tell us how big your fish is. Measure or estimate the "standard length", that is from the tip of the nose to the base of the tail fin, but not including the tail fin. Your fish will not grow much bigger, so this will tell us if adding a fish to this tank is feasible. 0 Quote Link to comment Share on other sites More sharing options...
