I am trying to plan out my next additions to my 65 gallon mangrove tank and I need something that will swim about mid height in the tank.

I have small archers, they stay at the top. I have a FW moray that is always at the bottom, and two Butis Butis that do go all over the place but for the most part they hide against the branches and background so you dont see them often.

I was thinking about Orange Chromides, being that they only get like 4". But I read that they will eat live plants. Mono's were another thought initially but they will get too big, also eat plants, and will require a switch to full marine eventually, which not all the other inhabitants will.

Any other ideas on what could do well in this setup that wont eat live plants?
 
i have two morays in my 125g tank and they are great but hard to feed had them for a week now and they havent eaten any help seeing that u have one, sry no help to the addition to the tank

Mine is eating frozen thawed krill. I use 24" hemostats to offer it down at his level, otherwise the archers or the crazy fish get to it long before it hits bottom :D.

I am going to see if I can get it to eat anything else though, as I read a diet of just krill isn't always good for them. Perhaps I can get it to eat a prepared frozen food that has a mixture of ingredients and supplements, like Formula One maybe.

I was going to suggest scats then you said mono's get to big lol. I believe scats get larger then monos.

Yeah, I think they do get bigger. Plus they also need full SW eventually, and I also am not too fond of their looks.

I have a puffer in another brackish tank, wonder if he would bother the archers if I moved him over. He doesn't bother the small knight goby or wasp fish hes in with now.
 
Hexanematichthys seemanni (Arius jordani)
Colombian Shark, White-Tipped Catfish, Silver-Tipped Catfish

most LFS call them Columbian sharks/catfish it will cruise like a aro

two pictures juv and adult they will "prowl" back and forth the midsection




I copied and pasted this part >>>>>>>>> Common name: Shark catfish, Colombian shark catfish, Tete sea catfish
Scientific name: Hexanematichthys seemanni
Synonyms: Arius seemani (old genus name), Arius jordani (junior synonym).
Size: Usually around 12-14" (30-35cm), but can reach 24" (61cm).
Origin: North, Central and South American rivers and estuaries.
Tank setup: Large brackish tank with plenty of open swimming space.
Compatibility: Predatory, likely to eat any fish small enough to fit in their mouths. Slightly territorial towards their own kind, peaceful with other fishes. Keep with large brackish fish, such as adult Scats or Monos.
Temperature: 21-26oC (70-79oF)
Water chemistry: Neutral to alkaline, slightly brackish to marine.
Feeding: Carnivore: live and frozen meaty foods, dry foods such as sinking catfish pellets can be used to balance the diet.
Sexing: Males are more slender than females.
Breeding: Not usually spawned in the aquarium, changes in salinity required. A mouthbrooder.
Comments: These fish are best kept in a small group. They are often seen for sale at 2-3" (5-7.5cm), but the potential size should be taken into account before buying. These fish are often sold from, and kept in, freshwater tanks when younger, but they should be converted to brackish water for their long term health. Low level brackish conditions (around s.g. 1.005) will suffice for young fish, but older specimens are best kept in stronger brackish conditions at around s.g. 1.015 or above.



It looks like a real damn shark

I was thinking about a shark cat. I wanted to keep it all asian/indonesian species to try to keep it as a biotope though, but maybe I'll let a south american species slip in, lol.
 
thos white tipped catfish/sharks require high temps i used to have 3 about a foot long they patrol the tank nicely but one time i was away and there was a power outage and my tank temp dropped below 60 degrees bc the window in the room was open poof they were dead it was very very sad i havent bought a monsterfish since.

Is that shark/catfish from south america? hmm i thought we had them here in some coastal waters

According to fishbase it looks like it's actually found throughout the Americas. I just said south American simply because I often see them referred to as Columbian Shark Cat's.
