Aggressive Boeseman Rainbowfish

HI I just started stocking my 75 gallon tank and I have a school of 6 porkchop rasboras and 5 Boeseman Rainbowfish. For the first few days they were all happy together and now one Rainbowfish has the whole tank to himself and the other rainbows are stuck by the bubble wand. The porkchops don't seem to bother the rainbow fish that is being aggressive but swim in a tight school. The aggressive rainbow swims in a circle around the tank then goes over the the remaining 4 and terrorizes them. What can I do?

 

I would add more BoesemanI - that should lessen the aggression.

 

Ok how many more. I want to add some algae eaters and Angelfish I don't want to overstock

 

What kind of algae eaters do you want?

In a 75 gal tank, you could have around 8-10 or so with an angelfish or two as well.

 

Well I can't keep a Pleco alive so I was going to try something else. What do you suggest?

 

What's your male to female ratio? Can you post a picture of the aggressive one? Occasionally pet stores sell hybrids mixed in with the regular bows, they can be more aggressive than normal.

 

I don't know Rita. How do I tell. I will try and get pics

Tell between males and females? The females are an olive/greenish color, males will be split with a blue front and yellow or orange back end.

 

We should try to figure out why you can't keep plecos alive before you add more fish.

Also, why do you want an algae eater? You're the best at controlling and preventing algae, but get them if you like them for more than just algae control.

 

I put out a link regarding my bn plecos dying. It was in a guppy tank. I fed them all types of foods shrimp pellets, algae wafers, cucumber. She ate for a month then died.

What size was this tank? Did she have any other symptoms before dying? Was she a newer fish to the tank?

 

I went through 4 different ones. My son who is three loves them. We all do in my family. Perhaps our favourite type. No symptoms. Did have stringy poop the last one.

20 gallon

 

Stringy poop is an indication of internal parasites. Did you get them all from the same place? It could be a bad batch at that place.

 

I am trying to get the aggressive one but he's fast

I am not very good at navigating this site. Starting to feel like an old lady that has no idea how to get things to work.

I thought so too however I have treated to no avail. Just didn't work. I am getting frustrated. I do have algae in two of my tanks. You can see the algae in the photos on the rocks and it is both brown and green only in that one spot. I have java moss on driftwood in that tank in the 20 gallon none.

If that’s a picture of the aggressive fish, then it’s a male and aggression isn’t too unusual when they’re establishing an initial “pecking order” or when courting a female. It seems from the other pictures that you have at least one female in there, but I can’t tell what the total ratio is. Gender ratio can determine how aggressive the fish are long term as well, based on their predisposition to start. You’ll want to have at least three males in the school, if there are only two the dominant male will “bully” the other. If you have just one male in a group of females he can end up being a bit too aggressive toward them as there’s no competition to divide his attention. As for females you can aI'm for a number that is equal or greater than the number of males in the tank (so if you have 3 males, go for 3+ females).

I think I only have one female. There are two that get very dark when fighting
