Picking the Right Type of Fish For Your Fish Tank

I’m starting to learn that one of the most important factors in enjoying the Aquarium Fish hobby is to be able to find the types of fish that you enjoy keeping.  Aquarium fish are not all the same.  In fact, that’s very far from the truth.

Just in the freshwater fish category alone, there are so many different species of fish and they each have their own little unique set of behaviors and personalities.  I think it is very important to learn as much as you can about all the different types of fish out there, and to try keeping a variety of them to see which ones you really like.

Every person will like different things so I think there is a lot of personal preference involved.  For example, the Oscars that I picked up a few weeks ago are really keeping me entertained.  There is just two of them in my tank, along with the Pleco I’ve got in there, and the two of them can be more entertaining to watch than my other tank which has over a dozen fish in it.

Today when I went to feed my Oscars, instead of eating the pellets I fed them they decided to hoard them and play with them.  Here’s a picture of one of my Oscars after it shoved like SIX pellets in it’s mouth and swam around with it’s mouth open.  It reminds me of when kids put a whole bunch of mashed potatoes in their mouth and then show you their food with their mouth open, hehe.

The other thing I noticed about the Oscars is that if I’m sitting here on my computer and I haven’t fed them yet, they eventually get tired of waiting for me and start making noises.  Sometimes they’ll just splash the water a bit to try to get my attention.  If I don’t pay attention, they’ll start to smack things in the tank.  I’m not really sure what they’re smacking, because every time I look they are off on the other side of the tank pretending like they didn’t do anything, but I know it’s them.  I think they may be hitting my filter intake pipe as it makes a CLANK sound when they hit it. 

I was also over at my brother Bart’s place today and I was checking out some of his fish and I noticed that there is a distinct difference in atmosphere in his 55 Gallon tank compared to mine.  He has a bunch of Tetra’s in there and Cray Fish, but what he doesn’t have is the Giant Danio’s and Pictus Catfish that I have in mine.  The Pictus Catfish and the Giant Danio’s I have really changed the atmosphere of my tank when I put them in.  They are both very fast swimming fish and whenever I go to sit down to watch the tank for a bit, they fly around the tank like crazy and all the other fish just go hide in the corner.  It’s really annoying.

I think I’m going to have to give them away, and I’m probably going to stick with calmer and smaller fish in that tank like the Tetra’s and Guppies I have in there now.  Maybe I’ll get an Angel Fish as well, as they are kind of neat to watch.  I also really did like my Female Betta’s before they were eaten, so maybe I’ll get some of those as well.

It’s almost impossible to figure out what kind of fish you’re going to enjoy keeping just by seeing them at the pet store, so I really think one of the best ways to figure out what you’ll want to keep is to just try picking up a couple of fish of different varieties and see what you end up enjoying.  Everyone is different and the person at the fish store will probably have a totally different preference from yours as will other aquarium hobbyists so I think it’s good to experiment on your own.

Both Tanks Fully Cycled Now

Well, I’ve tested my chemical levels multiple times in the last few days and it looks like both of my tanks are fully cycled now.  The Ammonia levels are now sitting at pretty much 0 ppm and Nitrites are starting to get converted to Nitrates as well.

Since my last post, what I’ve done is I’ve moved my Pleco from my 55 gallon tank and put him into my 46 Gallon tank with my two Oscars.  Eventually I’ll have to make some changes as a 46 Gallon is too small for two Oscars and a Pleco but for now they seem to be getting along quite nicely.

In my other tank, I have not seen any further deaths since the massacre that took the lives of 8 of my fish in one night.  Now that my 55 Gallon is fully cycled, I might think about stocking a few more smaller fish in there but I’m kind of contemplating getting rid of my Pictus Catfish and my Giant Danio’s and just getting some slow fish.  The Danio’s and Pictus are just so skittish that it kind of ruins the mood of the tank when they go flying around at warp speed nine.

8 Fish Vanish!

Two nights ago I had the weirdest thing happen in my 55 Gallon Tank.  Before I describe what happened, first I need to explain what fish were in the tank. Here’s a list of fish that I’ve had in the tank for the last few weeks:

2x Female Betta
1x Cardinal Tetra
2x Bala Shark
3x Pictus Catfish
2x Giant Danio
2x Oto Catfish

Besides the fact that the two Giant Danio’s would swim round super fast and sometimes freak out the other fish and the two Pictus Catfish were skittish when I would turn on/off the lights, all the fish seemed to be getting along quite nicely with no fin nipping or aggression.

Then, a few days ago I got a Free 46 Gallon Tank so I decided to get rid of my 20 Gallon tank and put the 46 Gallon in that spot in my room.  To do this I had to transfer the fish that were in my 20 Gallon into the 55 Gallon.  I didn’t think there would be any problem with this, considering all the fish in the 20 Gallon are peaceful fish.  Here is what I had in the 20 Gallon tank:

8x Cardinal Tetra (Small)
1x Oto Catfish
5x Guppies (Small)
1x Pleco

Ok, so I moved those fish into the 55 Gallon.  My main concern was that the 55 Gallon isn’t completely cycled yet so I knew I would have to really watch my Ammonia levels carefully.  However, I’ve been doing daily partial water changes due to the Ich problem I had and it’s not that bad so I figured even if the extra fish put more strain on the biological filter I could temporarily compensate by doing more frequent water changes.  A small price to pay to get a nice 46 Gallon tank setup in place of my small 20 Gallon.

Anyways, I put the fish in there and I kind of figured a couple of the small Tetras might go missing or die but I never expected what happened next.

The following day I check the tank and I noticed that one of my Bala Sharks had the top part of his tail nipped off.  I thought that was pretty odd since I didn’t add in any aggressive fish and the existing fish that have been in the tank were getting along fine.  Then I started looking around and I noticed that a whole bunch of fish were missing!

When I say a whole bunch, I mean EIGHT FISH!  Here’s the casualty list from one night:

2x Female Bettas… GONE!
1x Bala Shark… GONE!
1x Bala Shark… Missing top part of tail.
5x Cardinal Tetras… GONE!

What the heck happened!?  I am pretty sure my 3 Pictus Catfish may be to blame.  They must have gone into a major hunting expedition that night and ate 8 of my fish!  I was devestated to see my Female Bettas gone especially.  They were so fun to watch.

I checked and no the fish didn’t jump out of the tank.  My lid is pretty tightly placed and I looked around the aquarium to make sure they didn’t all jump out.  And no it wasn’t my cat either.  I’m keeping a close eye on the Pictus Catfish and if I find that they are killing all my fish at night, they might just end up getting relocated to the pond in my back yard!

Added More Fish to My Aquariums

I’ve added more fish to both of my Aquariums in the last week.  I bought 3 Cardinal Tetra’s, 3 Bala Sharks, 3 Otto Catfish, and one really cool looking Adonis Pleco.  For some reason I lost 2 Tetras and 1 Bala Shark the very first night, but the rest of the fish have had no problems and it’s been almost a week now.

I ended up putting one of the Otto’s in my 20 Gallon as I’m starting to grow some algae in there so I hope he starts to clean that up a bit.  Also, my younger brother Bart gave me 3 fairly sized Pictus Catfish and a Pleco the other day.  I put the 3 Pictus Catfish in my 55 Gallon tank and the Pleco in the 20 Gallon.  He can have a feast with all the algae in there.

Here are some pics:

I’ve been keeping an eye on my Ammonia, Nitrite and Nitrate Levels and finally in the last couple of days the Ammonia levels in my 20 Gallon have started to go down rather quickly, so it looks like my cycle in that tank is coming along nicely.  As for the 55 Gallon, the Ammonia has just started going up in the last few days and today I noticed my Nitrites have gone up so the Cycle is just beginning in that tank.

I’ll be keeping an eye on the Ammonia levels to make sure they don’t go up too high.  Also, I picked up this Filstar Zeolite Ammonia Remover Cartridge for my Rena Filstar xP3 Filter.  It’s supposed to help keep your Ammonia levels from getting too high in new Aquarium setups and from hitting sudden spikes later on.

I’ll measure my Ammonia levels over the next few days and report back how effective it is.
