Hello all,

                As the topic suggests I am looking for a pair of centre piece fish to enhance my new 130l tank. My current stock is 9 guppies(not fancy) , 9 copper harlequins and 15+cherry shrimp with a few Assassin snails.

The snails and the shrimp can be moved to accommodate the new arrivals into my smaller 54l but if possible I would like to keep them all in 1 place.

 

I've been looking at the German blue rams but I know I would have to move the shrimp and the water temp could be an issue.

 

Can any of you guys please offer up a few suggestions on compatibility that would work?

 

Thank you in advance

What's available where you are? If you give a location it might be possible to suggest some sources. Personally I'd look for some good quality Apistogramma, don't know what your water parameters are like but borellii are pH and temperature tolerant and a displaying male is as bonny a fish as any.

Ok I will pass on as much info as I can

Im in the Uk..have 3 good quality Fish stockists within a 20mile drive.

 

All water parameters are perfect

Current water temps are 25/26 degrees

Ph is 8.0

Kh is 11

Tank is heavily planted with cover and a gravel substrate.

 

Thank you for replying, im looking that fish up right now

That's quite a high pH, stilll within tolerable limits for borellii (just) but not for many other dwarf cichlids. I'll also suggest Peacock Gobies, migt be better suited to the pH, they're pretty cichlid-like in behaviour and stunning to look at. I'm surprised the Harlequins are happy at that pH to be honest.

Well the low PH reading on my API is 7.6 and the high one is 8. They are shoaling and look happy. Theres no stress and they don't look agitated or ill in any way. I had an issue with them feeding to start with but that's been sorted with some new food.

Thank you again for the fish advice. I will look those up

It would help to know the GH, as this is actually the most important parameter when one is considering soft or hard water fish.

You can get different readings using the low/medium/high range pH kits so I would use the one that fits your tap water best.  Then you will have consistency and will more easily see if it suddenly shifts from the norm.

By copper harlequin do you mean Trigonostigma hengeli?  The profile info says it is comfortable up to 7.5.  If your GH is not above moderately hard, I can see why they are OK.  Generally, though, one must keep in mind that the effects of too hard water on soft water fish may not be easily discernible, until the fish suddenly dies prematurely (meaning, not living a normal lifespan).  The accumulation of calcium in the kidneys can block them, causing the death; without dissection this is not apparent.  There was a study on cardinals about this in TFH back in the 1990's I believe, a translation from the original German study.  Baensch & Riehl mention it in the entry for the cardinal in Aquarium Atlas I and I have read the TFH article.  The article, and subsequent mention of the same issue by Stanley Weitzman elsewhere, suggests that most soft water fish are probably just as susceptible.  I'm not saying the pH isn't important too, it is, but usually this is going to follow the GH.  But not all wild caught fish are going to be as accommodating as the rasbora.

Ive checked my water supplier as I did this right at the start of my adventure with this hobby. The water is classed as moderately hard. I will grab a GH kit tomorrow and get the exact figures down.

Ok grabbed the API kit today.

 

KH = 11 as already known

GH = 17 which is 304.3ppm

 

Does this help with options?

Peacock Gobies for me, they're great. Little tube or bit of bamboo and they'll spawn away merrily. In the past I've just placed a thumb and finger over the ends of the tube to move the male and eggs to a rearing tank, soon as they hatch back he goes, just have to watch out for him breeding himself to death.
